Using the together rate, it is found that they would have finished the task in 8 days working together.
<h3>What is the together rate?</h3>
It is the sum of each separate rate.
In this problem, the rates are given as follows:
- Greg works four times as slower as Reid, that is, one security audit takes 40 days, hence his rate is of 1/40.
Then, the together rate is given by:


5x = 40
x = 8
They would have finished the task in 8 days working together.

Answer: 3/8 of the class went to the evening session.
Explanation:
So it says on Sunday 3/4 of an 8th grade class went to see the movie.But we do not know the real population of the 8th grade class. But is says that out of the 3/4 of the students that went to the movie have of them went in the afternoon so we will multiply 1/2 by 3/4 to find out how many people went to the afternoon session.
3/4 * 1/2 = 3/8 So we know that 3/8 of the 3/4 of the class went in the afternoon so we will now subtract 3/8 from 3/4 to find out what fraction went in the evening.
=
To think about it if half of the 3/4 of the class went in the afternoon then another have will go in the evening.
