7.5 is what percent of 8.76 - 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 8.76 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 8.76, so we can write it down as 100%=8.76.
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%=8.76
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%=8.76/7.5
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 8.76

100%/x%=8.76/7.5
(100/x)*x=(8.76/7.5)*x       - we multiply both sides of the equation by x
100=1.168*x       - we divide both sides of the equation by (1.168) to get x
100/1.168=x
85.616438356164=x
x=85.616438356164

now we have:
7.5 is 85.616438356164% of 8.76
