5/8 is greater then 7/12.
Explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 8 and 12 is 24
For the 1st fraction, since 8 × 3 = 24,
5/8=5x3/8x3=15/24
Likewise, for the 2nd fraction, since 12 × 2 = 24,
7/12= 7x2/12x2=14/24
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
15/24>14/24 or 5/8>7/12
