How do you convert a fraction to so they have a common denominator?

I assume you already know how to find the common denominator itself. Once you find the common denominator, you have to multiply top and bottom of each fraction by the same number, in such a way that the denominator is equal to the common denominator. For example: if you want to add 1/4 and 1/6, the common denominator is 12; to convert 1/4 to twelths, since you need to multiply the bottom part by 3 to convert it to 12, it follow that you multiply the top part by 3 as well - therefore, 1/4 = 3/12. Similarly, 1/6 = 2/12 (since you have to multiply the bottom by 2, you also multiply the top by 2).

How do you add mixed numbers with different denominators?
First convert them t top-heavy fractions. Treat these as you would ordinary fractions: find common denominator and so on. At the end, convert the top heave fraction back to a mixed fraction.
What is 46 over 63 - 3 over 11?
To calculate this sort of subtraction problem the two fractions have to be converted so that they share the same denominator - the number below the line. This is done by calculating the lowest common denominator they share. As 11 is a prime and 63 is not a multiple of it, then the lowest common denominator will be 63 x 11 = 693. * To convert the 46/63 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 11. This gives 506/693. * To convert the 3/11 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 63. This gives 189/693. Now we can subtract 189 from 506. That gives 317. * 317/693 As 317 is a prime, and 693 is not a multiple of it, that fraction can not be simplified.
What is one and three eighths as a fraction?
One and three eigths already is a fraction. If you want to convert a mixed fraction such as this one to an improper fraction, multiply the whole number by the denominator, and add the numerator. This will be the numerator of the result. Just copy the denominator (in this case 8) for the result. so basicly 11/8
3.45 as a fraction?
69/20 1) Convert the portion of the number that is smaller than 1 in a fraction. 0.45=45/100 2) In order to reduce this fraction, find and divide by the Greatest Common Factor (GCF). 45/5=9 100/5=20 so 45/100=9/20 3) Now, convert the whole number into a fraction with a common denominator. 3/1=60/20 4) Add the two fractions to get the answer. 60/20+9/20=69/20 5) To check the answer, divide the numerator by the denominator 69/20=3.45
Can any decimal that ends in the THOUSANDTHS place be written as a fraction with a denominator that is divisible by 2 and 5?
Any decimal that ends in the 1000ths place can be written as a fraction with a denominator of 1,000, so yes. If there are common factors you may be able to simplify it.
How do you change a fraction so they have the same denominator?
First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
How to change dissimilar fractions to similar fractions?
Note: numerator is the top part of the fraction, denominator is the bottom part. 1) Find a common denominator. It may be the least common denominator, but it need not be; just multiplying the denominators also gives you a common denominator, not necessarily the smallest one. 2) Convert each fraction so that it has this common denominator. This means multiplying numerator and denominator by the same number.
Can you show me examples of common denominator?
Find the LCM of the denominators. Example 1: 1/4 + 2/3 The LCM of 3 and 4 is 12, so the common denominator is 12. Convert each fraction to 12ths and add. Example 2: 1/8 + 5/6 The LCM of 6 and 8 is 24, so the common denominator is 24. Convert each fraction to 24ths and add.
How do you determine what fraction is greater than the other?
Find the least common denominator and convert them to equivalent fractions so that the denominators are the same. Choose the one with the greatest denominator.
How do you add fractions without the same denominator?
Find the LCM of the denominators. Example 1: 1/4 + 2/3 The LCM of 3 and 4 is 12, so the common denominator is 12. Convert each fraction to 12ths and add. Example 2: 1/8 + 5/6 The LCM of 6 and 8 is 24, so the common denominator is 24. Convert each fraction to 24ths and add.
Which fraction is bigger 5 eights or 7 fifteens?
To compare fractions, do one of the following: 1. Convert to a common denominator; in this example, that may be 120. (It need not be the least common denominator; any common denominator will do, so you can just multiply both denominators.) 2. Use a calculator to convert to decimal. In this case, 5 divided by 8, and 7 divided by 15.
How do you add mixed numbers with different denominators?
First convert them t top-heavy fractions. Treat these as you would ordinary fractions: find common denominator and so on. At the end, convert the top heave fraction back to a mixed fraction.
Is the fraction 8 9 smaller than 1 3?
no larger Convert to common denominator. 1/3 = 3/9. Compare the numerators 3<8 The fraction with smaller numerator when both fractions have a common denominator is the smaller one. So, 8/9 > 1/3, and the answer is no.
How do you answer fraction problems?
The best way to answer fraction problems is with a fraction that has the same denominator or a common denominator with those in the original problem. Typically you also need to reduce it so that the final answer does not contain an improper fraction.

What is 46 over 63 - 3 over 11?
To calculate this sort of subtraction problem the two fractions have to be converted so that they share the same denominator - the number below the line. This is done by calculating the lowest common denominator they share. As 11 is a prime and 63 is not a multiple of it, then the lowest common denominator will be 63 x 11 = 693. * To convert the 46/63 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 11. This gives 506/693. * To convert the 3/11 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 63. This gives 189/693. Now we can subtract 189 from 506. That gives 317. * 317/693 As 317 is a prime, and 693 is not a multiple of it, that fraction can not be simplified.
What is the fraction between 1 eighths and 1 sixteenths?
Convert both fractions to their common denominator which is 32. 1/8 = 4/32 and 1/16 = 2/32. So the fraction between the two is 3/32.
