Question

Which of the following options have the same value as 30% of 81? Choose 3 answers: A 30/100 x 81 B 0.3 x 81 C. 0.03 x 81 D. 3/10 x 81 E 30x 81

Answer 1

A 30/100 x 81

B 0.3 x 81

D. 3/10 x 81

Step-by-step explanation:

Given the expression:

`30\%\text{ of 81}`

Recall that a percentage is a part of 100.

Therefore: 30% = 30/100

`30\%\text{ of 81}=(30)/(100)*81\text{ (Option A)}`

Next, if we convert 30/100 to a decimal, we have that:

`(30)/(100)*81=0.3*81(\text{Option B)}`

From option A, if we cancel out a zero in the numerator and denominator, we have:

`(30)/(100)*81=(3)/(10)*81(\text{Option D)}`

The correct choices are A, B, and D.
