Question

7:

Yesterday, there were 80
problems assigned for math homework. Harry did 20%
of them correctly. How many problems did Harry get right?
​

Answer 1

First turn 20% into a decimal by dividing it by 100.

20% ⇒ 0.20

Now multiply 80 by 0.20.

0.20 × 80 = 16

Answer:

20% of 80 is 16, so Harry got 16 questions correct.

Answer 2

16

Explanation:

20% = 0.20

80 x 0.20 = 16

P.S. Harry needs to study ;)
