The question is "subtract 3 7/8 from 5 1/16" Since 1/16 is less than 7/8=14/16, we need to borrow, so we will do 4 17/16" - 3 14/16" =(4-3) (17-14)/16 = 1 3/16"

First, you need the common denominator -- so 3 7/8 = 3 14/16 5 1/16 - 3 14/16 Change: 5 1/16 to 4 17/16 4 17/16 - 3 14/16 = ?

The way to decide this answer is to change all of these fractions so that they have the same denominator. In other words, find the least common multiple. 7/8 = 14/16 5/8 = 10/16 3/4 = 12/16 9/16 = 9/16 Which is the smallest numerator?
