75.5 is what percent of 86.07 - 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 86.07 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 86.07, so we can write it down as 100%=86.07.
4. We know, that x% equals 75.5 of the output value, so we can write it down as x%=75.5.
5. Now we have two simple equations:
1) 100%=86.07
2) x%=75.5
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%=86.07/75.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 75.5 is what percent of 86.07

100%/x%=86.07/75.5
(100/x)*x=(86.07/75.5)*x       - we multiply both sides of the equation by x
100=1.14*x       - we divide both sides of the equation by (1.14) to get x
100/1.14=x
87.719298245614=x
x=87.719298245614

now we have:
75.5 is 87.719298245614% of 86.07
