Try it... Let's take 7/5 as a starter (decimal 1.4). This becomes 8/6 (decimal 1.33), so your value decreases.

What happens when decrease in numerator and increase in denominator?
The fraction gets smaller or increases, depending on whether the numerator and denominator are positive or negative.
What happens to the fraction if the denominator and numerator are increased by the same amount?
Assuming a proper fraction which is positive (value between 0 and 1), it increases; asymptotically tending to 1 as the amounts that you increase by become larger. If it is negative you must select a negative numerator and a positive denominator. Then it behaves as above. Otherwise you could hit division by 0.
Is the fraction 2 over 8 greater than 1 over 4?
The fraction 2/8 is equivalent to 1/4, as 1*2=2 and 4*2=8. By the way, you can multiply a fraction like 1/4 by 2/2 because 2 divided by 2 is one, and so you are only changing the numbers displayed, but the value of the fraction stays the same, as the numerator and denominator increase at the same rate, proportionally.
What fraction is less than 1 over 10?
Increase the denominator, the number on the bottom of the fraction. 1/11 is smaller for example, 1/12 is smaller again. Etc..
What are some factors influencing the numerator and denominator t-statistic?
Several factors influence the value obtained for a t statistic. Some factors affect the numerator of the t statistic and others influence the size of the estimated standard error in the denominator. For each of the following, indicate whether the factor influences the numerator of dominator of the t statistic and determine whether the effect would be to increase the value of t (farther from zero) or decrease the value of t (closer to zero). In each case, assume that all other factors remain constant. a. Increase the variability of the scores. b. Increase the number of scores in the sample. Increase the difference between the sample mean and the population mean.
What will happen when you divide by a fraction?
If the dividend (the number being divided into) is zero, then there is no change in value as the result is also zero; Otherwise:if the fraction is a proper fraction (the numerator is less than the denominator) then the (absolute) value of the dividend will increase; otherwiseif the fraction is an identity (the numerator equals the denominator) then the value of the dividend will not change; otherwisethe fraction is an improper fraction (the numerator is greater than the denominator) and the (absolute) value of the dividend will decrease.
How can both the numerator and denominator of a fraction increase and yet the fraction names the same amount?
That's exactly the result when the numerator and denominator of the fraction are both multiplied by the same number.
What happens when decrease in numerator and increase in denominator?
The fraction gets smaller or increases, depending on whether the numerator and denominator are positive or negative.
Why do the parts of a whole get smaller when the denominator increaces and larger when the numerator increaces?
You have to view fractions as division problems: to convert a fraction to a decimal, you divide the numerator by the denominator. As such, when you increase the denominator, you are dividing by a larger value, so your quotient will be smaller. For example, if you have the fraction 1/10, 1 divided by 10 is 0.1. If you have the fraction 1/100, 1 divided by 100 is 0.01. When you increase the numerator, this pattern reverses. 1/10, 1 divided by 10, is 0.1. 10/10, 10 divided by 10, is 1.
Writing mixed numbers as decimal. Rounded to the nearest hundredth?
This is a few problems. To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. To convert an improper fraction to a decimal, divide the denominator into the numerator. To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the thousandths place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.

What will happen to a fraction if you add four to the denominator?
The fraction will increase.
When you estimat the sum of two mixed numbers what do you do?
Round them off. If the fraction is less than 1/2 (the numerator is less than half of the denominator), eliminate it. If the fraction is equal to or greater than 1/2 (the numerator is equal to or greater than half the denominator), increase the whole number by one and eliminate the fraction. The estimated sum of 2 and 1/3 + 3 and 3/4 is 6.
What happens to the size of a positive fraction when the the numerator is increased by 1?
The size increase.
What is three and three fourths plus two and seven twenty eighths equal?
The answer is 6. Here's how to determine that: 1. Start with the original fractions of 3 3/4 + 2 7/28 2. Obtain a common denominator so they can be added together. To do that, multiply the numerator of the fraction with the smallest denominator by the same value it takes to increase the denominator to the same value as the other denominator. In english: in the fraction 3/4, "3" is the numerator and "4" is the denominator. We have to get the "4" to match the larger denominator ("28") of the 7/28 fraction. To do that, look at both denominators ("4" and "28") and determine if the smaller denominator ("4") can be multipled to equal the larger denominator ("28"). Since we know that multiplying 4 by 7 equals 28, we know that we can make the denominators equal by multiplying the 3/4 fraction by 7. So, doing so, we then have a fraction that is 21/28. Both numbers in the fraction are multipled by the same amount. 3. So, now you have 3 and 21/28 + 2 and 7/28. 4. Add the fractions (21/28 and 7/28) together, which gives you 28/28. Since the result is a whole number (a fraction with matching numerator and denominator), we no longer need to write it as a separate fraction. Therefore, the new formula looks like this: 3+2+1 (the 1 was originally 28/28). Added together, the result is 6.
How you change a mixed number to a decimal?
A "mixed number" has a whole number followed by a fraction part, which is the ratio between a "numerator" (on top) and a "denominator (on the bottom). If the fraction is "improper" (i.e. with a numerator that is larger than the denominator, such as 27/20), then first convert it to a proper fraction and increase the whole number accordingly. For example, "3 and 27/20" becomes "4 and 7/20" by subtracting the denominator from the numerator (bottom from top) as many times as possible, and adding one to the whole number each time. This gives a whole number of 4.0 with a fraction part of 7/20. Next, we must convert the fraction part to decimal digits following a decimal point, by changing the denominator to some power of ten, such as 10 or 100 or 1000, etc. This is done by multiplying both the numerator and the denominator by the same number. Using the fraction 7/20 as an example, we need to multiply both the numerator and the denominator by a number that changes the denominator to a power of ten. If we multiply 20 by 5, the denominator becomes 100. Multiplying both numerator and deminator by 5 will change the fraction part, 7/20, to 35/100, gives 0.35 for the decimal digits following the whole number (4). Thus, "4.35" is the final result for 4 and 7/20 (or 3 and 27/20). This decimal number, 4.35, may also be written as 4.350 or 4.3500 or 4.35000..., etc. but we usually drop the repeating zeroes that follow the last non-zero digit. If, however, the denominator cannot be multiplied by something to get a power of ten (i.e. if it has prime factors other than 2 and 5), then the decimal part will not end with repeating zeroes, but it will have a repeating decimal part, such as "33333..." or "27272727..." that goes on forever. (All "rational" numbers are repeating decimals.) To get this repeating decimal, you will need to do long division (or use a calculator). For example, if the "mixed number is "4 and 7/22" then then the fraction part is obtained by dividing 22 by 7, and the result is "4.318181818..." .318181818181818181818... ________________ 22 ) 7.0000000000.... - 6.6 ____ .40 - .22 _______ 180 - 176 _______ 40 - 22 _________ 180 - 176 _________ 40 and so on!
If 5 is added to the number and denominator of 57 by how much is the fraction increased?
The fraction changes from 57/1 to 62/6 which is a decrease, not an increase.
