Estimate 51% of 18.

(A)9

(B)4

(C)13

(D)19

Answer 1

(A)9

Explanation:

If you weren't using a calculator, you know that half, or 50% of 18 is 9, and if it is 51% it will also be around 9. Therefore A is the correct answer.

Answer 2

(A) 9

Explanation:

First, change the percentage sign into decimal: 51% = 51/100 = 0.51

Multiply 0.51 with 18

0.51 x 18 = 9.18

Note that it is asking for an estimate, and so round to the nearest whole number.

9.18 rounded to the nearest whole number is 9

(A) 9 is your answer.
