67.7 is what percent of 87.5 - 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 87.5 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 87.5, so we can write it down as 100%=87.5.
4. We know, that x% equals 67.7 of the output value, so we can write it down as x%=67.7.
5. Now we have two simple equations:
1) 100%=87.5
2) x%=67.7
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%=87.5/67.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 67.7 is what percent of 87.5

100%/x%=87.5/67.7
(100/x)*x=(87.5/67.7)*x       - we multiply both sides of the equation by x
100=1.2924667651403*x       - we divide both sides of the equation by (1.2924667651403) to get x
100/1.2924667651403=x
77.371428571429=x
x=77.371428571429

now we have:
67.7 is 77.371428571429% of 87.5
