Question

4/5. 16/20 which is greater​

Answer 1

Find the least common denominator or LCM of the two denominators:

LCM of 20 and 5 is 20

For the 1st fraction, since 20 × 1 = 20,

16 /20   =   16 × 1  / 20 × 1   =   16  / 20

Likewise, for the 2nd fraction, since 5 × 4 = 20,

4 /5   =   4 × 4  / 5 × 4    =   16  / 20

16 /20   =   16  / 20   or  16  / 20   =   4  / 5
