A student completed 1/4 of a workbook in 3/5 hour.He plans to work for 1 more hour at the same rate.What Fraction of the workbook should he expect to complete in 1 hour?



Answer :

workbook =x
1/4   3/5
 x    5/5 (1 hour)
then x=(5/5 * 1/4):3/5
x= 5/20 * 5/3 
x=1/4 *5/3
x= 5/12

The fraction of the workbook he should expect to complete in 1 hour is 5/12

How to determine the fraction of work?

The student's rate is given as:

1/4 of a workbook in 3/5 hour.

The rate in this scenario is calculated using:

Rate = Workbook/time

So, we have:

Rate = 1/4 / 3/5

Express as product

Rate = 1/4 * 5/3

Evaluate

Rate = 5/12

This means that she would complete 5/12 of the workbook in 1 hour

Hence, the fraction of the workbook he should expect to complete in 1 hour is 5/12
