79.99 is what percent of 9100 - 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 9100 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 9100, so we can write it down as 100%=9100.
4. We know, that x% equals 79.99 of the output value, so we can write it down as x%=79.99.
5. Now we have two simple equations:
1) 100%=9100
2) x%=79.99
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%=9100/79.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79.99 is what percent of 9100

100%/x%=9100/79.99
(100/x)*x=(9100/79.99)*x       - we multiply both sides of the equation by x
100=113.76422052757*x       - we divide both sides of the equation by (113.76422052757) to get x
100/113.76422052757=x
0.87901098901099=x
x=0.87901098901099

now we have:
79.99 is 0.87901098901099% of 9100
