Answer:
Step-by-step explanation:
The first step is to figure out what the % is on the right.
The total is 100%
The left side is 60%
The right side is 100% - 60% = 40%
Now the 40% represents 28 students
The total number of students is 100%
40%/100% = 28/x Cross multiply
40% x = 28 * 100% Divide both sides by 40%
x = 28 * 100 / 40
x = 70
So the total number of students is 70
60% of them are on the left. 60/100 * 70 = 42
There are 42 students on the left.
