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

 A, C, D

(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

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
