You spend 15 minutes doing homework. You spend 3 hours watching television. Write the ratio of the amount of time spent doing ho
german

The ratio of the amount of time spent doing homework to the amount of time spent watching TV is 1/12.

  • The time spent on doing the homework is 15 minutes.
  • The time spent watching television is 3 hours.
  • To calculate the ratio, we must have the same units for both quantities.
  • We have to convert the time spent watching television from hours to minutes.
  • 1 hour is 60 minutes.
  • 3 hours has 3*60 minutes.
  • 3 hours have 180 minutes.
  • So, the time spent watching television is 180 minutes.
  • The ratio of the amount of time spent doing homework to the amount of time spent watching TV is 15/180.
  • We need to simplify the fraction.
  • 15/180 is equal to 1/12.
  • Thus, the ratio of the amount of time spent doing homework to the amount of time spent watching TV is 1/12.
