Question

A plumber needs to drill a hole that is slightly larger than 3/16 inch in diameter. Which measure is smallest but still larger than 3/16.
A) 5/32 B) 5/16 C) 13/64 D) 9/32

Answer 1

3/16= 12/64
a= 10/64
b=20/64
c=13/64
d=28/64
well, a is smaller, b is larger, c is larger, and d is larger, so we have B C D to work with. you can tell C is the smallest of the group B C D

C is the smallest that is still larger than 3/16
