How do you find out which fraction is larger than the other?

Answer 1

First you must find the lowest common denominator (LCD) [see Related Question below], and convert both fractions.

Then, once the denominators are the same, compare numerators to see which is larger.

Example:

which is bigger 2/3 or 6/15 ?

The LCD is 15 so you convert 2/3 to 10/15.

Now compare. 10/15 (aka 2/3) is obviously bigger than 6/15.

You have your answer.

AGAIN - see related question below to see how to find LCD.

First, find a common denominator (the number on the bottom of the fraction) of the two fractions. For example if you have 2/3 and 1/2, you can do:

2x2=4, and 3x2=6 so you get 4/6 for the first fraction.

1x3=3, and 2x3=6 so you get 3/6 for the second fraction.

Then you look at the numerators (the number on the top of the fraction).

4 is bigger than 3, so 4/6 is bigger than 3/6. Therefore, 2/3 is bigger than 1/2.
