7.5 is what percent of 79.25 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 79.25 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 79.25, so we can write it down as 100%=79.25.
4. We know, that x% equals 7.5 of the output value, so we can write it down as x%=7.5.
5. Now we have two simple equations:
1) 100%=79.25
2) x%=7.5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=79.25/7.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.5 is what percent of 79.25

100%/x%=79.25/7.5
(100/x)*x=(79.25/7.5)*x       - we multiply both sides of the equation by x
100=10.566666666667*x       - we divide both sides of the equation by (10.566666666667) to get x
100/10.566666666667=x
9.4637223974763=x
x=9.4637223974763

now we have:
7.5 is 9.4637223974763% of 79.25
