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
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
