91 is what percent of 94.5 - 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 94.5 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 94.5, so we can write it down as 100%=94.5.
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%=94.5
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%=94.5/91
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 94.5

100%/x%=94.5/91
(100/x)*x=(94.5/91)*x       - we multiply both sides of the equation by x
100=1.0384615384615*x       - we divide both sides of the equation by (1.0384615384615) to get x
100/1.0384615384615=x
96.296296296296=x
x=96.296296296296

now we have:
91 is 96.296296296296% of 94.5
