Hi could someone plz help me- I will do anything I been stuck on this one for too long..:(

22.22%

Step-by-step explanation:

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

Total time spent = 2 + 1 +

                            = 3 + 1.5

                            = 4.5 hours

Now percent of time spent in doing laundry = × 100

= 22.22%

He spent 22.22% time in doing laundry.
