Question

Determine which fraction is larger: 6/7 or 4/5

Answer 1

6/7

Explanation:

find the least common multiple of 7 and 5:

7,14,21,28,(35)

5,10,15,20,25,30,(35)

7x5=35 and 5x7=35

So multiply the denominator and numerator of 6/7 by 5, so 30/35

and multiply the denominator and numerator of 4/5 by 7, so 28/35.

30 is bigger than 28, so 30/35 is greater than 28/35.

Therefore, 6/7 is greater than 4/5
