Question

Ivan took 2 1/2 hours to clean the kitchen he took 3/8 hours to clean the bedroom how much longer does it take Ivan to clean the kitchen

Answer 1

Ivan took 17/8 hours longer to clean the kitchen

Explanation:

The time it took Ivan too long, would be the difference between the time he took to clean the kitchen by the time he took to clean his bedroom.

Then,

`2(1)/(2)-(3)/(8)=(17)/(8)`

Ivan took 17/8 hours longer to clean the kitchen
