Four buttons have diameters of 5/8 3/4, 9/16, and 7/8 inches. Which button is smallest?
A) 7/8 B) 5/8 C) 3/4 D) 9/16
i wanna say the answer is 3/4

math  Reiny, Thursday, June 26, 2008 at 9:33pm
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.

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?
