Question

5. Kamala worked for 7 1/2 h. She spent 2/3 of the time on her computer. How long was she on her computer?​

Answer 1

She was 5 hours on her computer

Number of hours worked =
`7(1)/(2)`

This is an improper fraction so first we convert it

`7(1)/(2) = > (15)/(2)`

Time spent on her computer =
`(2)/(3)`
`of working hours`

∴ time spent on computer = (15/2)*(2/3)

= 5 hours

Answer 2

5 hrs

Explanation:

7 1/2 hours equates to 450 minutes total

2/3 of 450 = 300 total minutes

turning the minutes back into hours, 300 / 60 = 5
