74.25 is what percent of 109.17 - 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 109.17 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 109.17, so we can write it down as 100%=109.17.
4. We know, that x% equals 74.25 of the output value, so we can write it down as x%=74.25.
5. Now we have two simple equations:
1) 100%=109.17
2) x%=74.25
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%=109.17/74.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74.25 is what percent of 109.17

100%/x%=109.17/74.25
(100/x)*x=(109.17/74.25)*x       - we multiply both sides of the equation by x
100=1.470303030303*x       - we divide both sides of the equation by (1.470303030303) to get x
100/1.470303030303=x
68.013190436933=x
x=68.013190436933

now we have:
74.25 is 68.013190436933% of 109.17
