Question

A student spent 2 hours studying, 1 hour doing laundry, and 1 ½ hours watching television. What percentage of time was spent doing laundry?

Answer 1

Total hours working = 4.5 hrs
hours doing laundry = 1 hr

Percentage of time doing laundry = 1/4.5
Percentage of time doing laundry = 22.22%

Answer 2

22.22%

Explanation:

A students spent 2 hours studying, 1 hour doing laundry, and
`1(1)/(2)` hours (
`(3)/(2)` hours) watching television.

Total time spent = 2 + 1 +
`(3)/(2)`

= 3 + 1.5

= 4.5 hours

Now percent of time spent in doing laundry =
`(1)/(4.5)` × 100

= 22.22%

He spent 22.22% time in doing laundry.
