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

Answer:

22.22%

Step-by-step explanation:

A students spent 2 hours studying, 1 hour doing laundry, and $1\frac{1}{2}$ hours ( $\frac{3}{2}$ hours) watching television.

Total time spent = 2 + 1 + $\frac{3}{2}$

                            = 3 + 1.5

                            = 4.5 hours

Now percent of time spent in doing laundry = $\frac{1}{4.5}$ × 100

= 22.22%

He spent 22.22% time in doing laundry.
