Multiple Choice Questions
1. Simplify the fraction 15/20 to its lowest terms.
A) 1/2
B) 3/4
C) 2/3
D) 5/10
Answer: B) 3/4
Rationale: Divide both numerator and denominator by their
greatest common factor (5): 15 ÷ 5 = 3; 20 ÷ 5 = 4. The
simplified fraction is 3/4.
2. Which fraction has the largest value?
A) 1/150
B) 1/100
C) 1/200

A) 0.25
B) 0.333
C) 0.375
D) 0.38
Answer: C) 0.375
