rewrite each with a common denominator of 16
5/8 = 10/16
3/4 = 12/16
9/16 = 9/16
7/8 = 14/16
Can you tell now?
or
change each fraction to a decimal by dividing top by bottom.
5/8 = 10/16
3/4 = 12/16
9/16 = 9/16
7/8 = 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?
7/8 = 14/16
5/8 = 10/16
3/4 = 12/16
9/16 = 9/16
Which is the smallest numerator?

Right. The smallest button is 9/16 inch.
