Which is bigger 7/8 or 13/16
salantis [7]
To compare these fractions, bring them to the same denominator. Expand the fractions to bring them to the common denominator (LCM):

7/8 = (2 * 7) / (2 * 8) = 14/16
13/16 = (1 * 13) / (1 * 16) = 13/16

Same denominator fractions sorted ascending:

13/16 < 14/16

Initial fractions in ascending order:

13/16 < 7/8
