91 is what percent of 207 - 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 207 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 207, so we can write it down as 100%=207.
4. We know, that x% equals 91 of the output value, so we can write it down as x%=91.
5. Now we have two simple equations:
1) 100%=207
2) x%=91
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%=207/91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 91 is what percent of 207

100%/x%=207/91
(100/x)*x=(207/91)*x       - we multiply both sides of the equation by x
100=2.2747252747253*x       - we divide both sides of the equation by (2.2747252747253) to get x
100/2.2747252747253=x
43.961352657005=x
x=43.961352657005

now we have:
91 is 43.961352657005% of 207
