What does two eighths plus three sixths equal?

2/8 + 3/6 First, you have to make the denominators equal(the number on the bottom, so in this case the 8 and the 6). This is called finding the LEAST COMMON DENOMINATOR. 8 and 6 both go into 24 with no remainder To get the denominators to be 24, you have to multiply 8 by 3 and 6 by 4. Now, since you multiplied the denominators by a number, you have to multiply the numerator with that same number. 2 * 3 = 6 and 8 * 3 = 24 3 * 4 = 12 and 6 * 4 = 24 12/24 + 6/24 Now you can add the fractions together! Since the denominators are equal, add the numerators together. 6 + 12 = 18 The denominator remains the same so the answer is: 18/24


How do you multiply fractions when the denominators are both the same?

As normal: numerator x numerator over denominator x denominator: eg 4/9 x 6/9 = 24/81 which can be simplified to 8/27


What is 7 over 8 minus 2 over 3?

5 over 24. [If you do not understand how to get that answer, here is how. To subtract fractions you must find the common denominator. In this problem you must find the common denominator between 8 and 3. They both can multiply into 24 so that is your common denominator. Now 8 times 3 will give you the denominator of 24, but you must also multiply the 7 by 3 to make the fraction the same. The first fraction will be 21/24. The next fraction will be 16/24 because 2 times 8 is 16 and 3 times 8 is 24. Now all that you have to do is subtract the numerators. 21 - 16 = 5 so your answer is 5/24.]


How Do You Make Fractions Have The Same Denominators?

You need to find the lowest common denominator. For example- 1/6 + 2/12 = 2/12 + 2/12=4/12 you need to multiply the 6 two times to get 12 and what you do to the bottom you always do to the top so you multiply 1 by 2 and get 2!


How do you subtract and simplify 5 over 18 minus 7 over 24?

In order to subtract, the denominators must be the same. The easiest way is to multiply 18 and 24, which equals 432. You will also have to multiply the numerators. Think of it like this: 24*(5/18) and 28*(7/24). You are multiplying the fraction as a whole. So, 24*5=120 and 18*7=126 Now the fractions are 120/432 and 126/432. Subtract them, and you get -6/432. To simplify, find a common number that both the numerator and denominator can divide by. Let's try 6. -6/6 = -1, and 432/6 = 72. Your simplified fraction is -1/72.

What is three fourths of 24?

First find 1/4 by dividing by 4: 24/4 = 6 Then multiply by 3 to find 3/4 = 18 When finding a fraction of an amount the general rule is to divide by the denominator then multiply by the numerator.


What is the common denominator of 18 and 24?

Is 24 over 27 and 16 over 18 proportional?

Yes, and they are the same fraction when reduced 24/27 = 8/9 ( divide numerator and denominator by 3) 16/18 = 8/9 ( divide numerator and denominator by 2)


How do you rewrite a fraction so it can have the same common denominator?

When adding or subtracting fractions with different denominators, changing the denominators so that they have a common denominator is a simple process. Example: 1/3 + 1/8 What you want to do first is multiply 3 by 8, 3*8=24. This will be your common denominator. Next multiply 1/3 by 8/8 so that your answer will have 24 as the denominator. 1/3*8/8=8/24 Now repeat this process with 1/8 by multiplying it by 3/3 to get your 24 denominator. 1/8*3/3=3/24 Now you have both fractions with the same common denominator, all that is left is to add. 8/24+3/24=11/24 And there is your answer.

What Is 5 over 6 - 3 over 8?

11 over 24 (11/24) Here's how: You need to find a common denominator. The lowest common denominator is 24, but you can use any common denominator to subtract. So convert 5/6 to 24ths: multiply numerator and denominator by 4 = 20/24, then multiply numerator and denominator of 3/8 by 3 = 9/24. Now subtract 9 from 20 = 11, which is the numerator of the difference: 11/24. This is already in simplest form.

Divide 7 with 24 and change the answer into a fraction?

Now multiply each fraction by 1, note that the denominator of 7/24 is already 24


Is three sixths greater than five eighths?

Yes, five sixths is definitely greater than three eighths. We can prove this by changing the fractions to share a common denominator (ie. the number at the bottom of the fraction is the same for both) If we use a denominator of 24, which can be divided by both 6 and 8, we can determine which of the fractions are bigger. So, if we multiply 6 x 4 to get 24, we must also multiply the numerator (5) by 4. 5 x 4 = 20 ------------- 6 x 4 = 24 Now we know that with a denominator of 24, the fraction becomes twenty twenty-fourths. We now multiply the 8 x 3 to get 24, doing the same to the numerator of that fraction (3). 3 x 3 = 9 -------------- 8 x 3 = 24 Now we know that with a denominator of 24, the fraction becomes nine twenty-fourths. So, which is bigger? 20 9 --- > --- 24 24
