Which is greater 3/7 or 7/12

3/7=36/84

7/12=49/84

So 7/12 is greater.

You may find this answer by finding the common denominator for both of them.

Find the LCM, and we'll use the listing method.

7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84

12: 12, 24, 36, 48, 60, 72, 84, 96

84 is the LCM.

Now multiply 3 as many times you did to find the denominator, which is 12 times.

3 x 12 = 36.

Multiply 7 as many times you did to find the denominator, which is 7 times.

7 x 7 = 49.

So:

36/84

49/84

Obviously, 49/84 is larger.
