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
As normal: numerator x numerator over denominator x denominator: eg 4/9 x 6/9 = 24/81 which can be simplified to 8/27
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.]
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.
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!
You find the least common denominator, which is 24 8x3=24 and 3x8=24. Multiply the numerator and denominator to get the same number.
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.
A common denominator is 72.
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)
72
To rewrite a fraction so it can have the same common denominator as another fraction, you need to find the least common multiple (LCM) of the denominators of the two fractions. Once you have the LCM, you can then rewrite each fraction with the common denominator by multiplying the numerator and denominator of each fraction by the appropriate factor. This process ensures that both fractions have the same denominator, allowing for easier comparison or addition/subtraction.

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.
As normal: numerator x numerator over denominator x denominator: eg 4/9 x 6/9 = 24/81 which can be simplified to 8/27
21/24 and 20/24
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
