Question

Harry worked seven hours last week this is 1/3 as many hours as Aiden worked how many hours did Aidan work

Answer 1

7 hours is 1/3 of what?
Multiply 7 by 3.
7 * 3 = 21
Answer: 21 hours.

Answer 2

The answer would be 21 hours. Aiden worked 21 hours.

Pretty much, if 7 is 1/3 of how many hours Aiden worked, then all you do is multiply 7 by 3.

Hope that helps!
