Question

Which is the most reasonable estimate for 30% of 72?

Answer 1

A. 7 B. 14 C. 21 D. 28

Answer 2

30% means (30/100)

so calculate (30/100)*72 and pick the closest answer

Answer 3

I would say 21

Answer 4

i go with a different definition:

1% = 1 part out of 100 parts.

if we divide 72 into 100 parts, then we know the value of 1%. then we simply add up 30 of them.

30 (72/100)

same result since multiplication is commutative/associative.
