79 is what percent of 86.2 - 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 86.2 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 86.2, so we can write it down as 100%=86.2.
4. We know, that x% equals 79 of the output value, so we can write it down as x%=79.
5. Now we have two simple equations:
1) 100%=86.2
2) x%=79
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%=86.2/79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79 is what percent of 86.2

100%/x%=86.2/79
(100/x)*x=(86.2/79)*x       - we multiply both sides of the equation by x
100=1.0911392405063*x       - we divide both sides of the equation by (1.0911392405063) to get x
100/1.0911392405063=x
91.647331786543=x
x=91.647331786543

now we have:
79 is 91.647331786543% of 86.2
