Question

Margie did math homework for 25 minutes science homework for 60 minutes and took a break for 15 minutes write a percent to represent the portion of time that Margi spent on science homework

Answer 1

Margie spent 60% of time in doing science Homework

Explanation:

Given:

Time spent in doing maths homework = 25 minutes

Time spent in doing science homework = 60 minutes

Break Time = 15 minutes

To Find:

A percent to represent the portion of time that Margie spent on science homework = ?

Solution:

Let the portion representing the portion of time that Margie spent on science homework be x

The total time spent in doing both maths and science homework and in break time = Time spent in doing maths homework + Time spent in doing science homework + Break Time

The total time spent in doing both maths and science homework and in break time = 25 +60 +15 = 100 minutes

Then

x =
`\frac{\text{time spent in doing science home work}}{\text{total time spent}} * 100`

x =
`(60)/(100) * 100`

x = 60%
