Question

Is 5/8 more than 11/20

Answer 1

Yes, because in order for 5/8 to have the same denominator as 11/20, you multiply 5 and 8 by 2.5, which equals 12.5/20.

Answer 2

5/8 is more than 11/20

If we find the lower common multiple of the denominators which is 160 then we can multiply the top numerators by the opposite denominators

5x20=100
11x8=88

We now have
$\frac{100}{160} and \frac{88}{160}$

The one on the left is simplified to 5/8 and the right is simplified to 11/20
