Which of the following options have the same value as 15% of 20?

A. 3/20 ⋅ 20

B. 15 ⋅ 20

C. 0.15 ⋅ 20

D. 15/100 ⋅ 20

E. 15 ⋅ 0.02

(choose 3 answers!)

Answers are: A, C, D

Note how

(3/20) * 20 = 0.15*20 = 3

0.15*20 = 3

(15/100) * 20 = 0.15*20 = 3

all expressions lead to the same result of 3

another thing to notice

3/20 = 15/100 = 0.15 = 15%

which are multiple ways to say the same thing just in a different form
