70.8 is what percent of 91.71 - 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 91.71 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 91.71, so we can write it down as 100%=91.71.
4. We know, that x% equals 70.8 of the output value, so we can write it down as x%=70.8.
5. Now we have two simple equations:
1) 100%=91.71
2) x%=70.8
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%=91.71/70.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70.8 is what percent of 91.71

100%/x%=91.71/70.8
(100/x)*x=(91.71/70.8)*x       - we multiply both sides of the equation by x
100=1.2953389830508*x       - we divide both sides of the equation by (1.2953389830508) to get x
100/1.2953389830508=x
77.199869152764=x
x=77.199869152764

now we have:
70.8 is 77.199869152764% of 91.71
