13. Which one of the following examples represents a proper fraction?
O A. 15/22
O B. 8/8
O C. 12/9
OD. 3/2

15/22 is the only proper fraction because its numerator (the top number) is less than the denominator (the bottom number).

Why the other answers aren’t proper:
8/8 may look like a proper fraction, but it isn’t. Proper fractions are also supposed to be less than 1, but this fraction is equivalent to 1. Also 12/9 and 3/2 are both improper fractions because their numerators are bigger than their denominators.

The answer is A because it’s the only answer where the top number is less then the bottom

Well let’s see here we need nuts and more nuts and probably more nuts so why not‍♂️
