Question

The pie chart below shows the portion of time Lisa spent on doing homework in each subject last week. If Lisa spent 2 hours on Mathematics, about how many hours did Lisa spend on homework altogether

Answer 1

pet the lisa spend is M

the amount of time lisa spent on watching television was 3 hours more than twice the time she spent on doing her mathematics homework.

lisa spent on watching television = 2M + 3hrs

Total time spent on these two activities = M + 2M + 3

• = 3M + 3 hrs

• 3 M + 3 = 30

• => 3M = 27

• => M=9

lisa spent on doing her mathematics home work = 9 hrs

Answer 2

Answer:

the amount of time lisa spent on watching television was 3 hours more than twice the time she spent on doing her mathematics homework.

lisa spent on watching television = 2M + 3hrs

Total time spent on these two activities = M + 2M + 3

= 3M + 3 hrs

3 M + 3 = 30

=> 3M = 27

=> M=9

lisa spent on doing her mathematics home work = 9 hrs
