What is 90.72 percent of 129.7 - 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 129.7 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 129.7 is 100%, so we can write it down as 129.7=100%.
4. We know, that x is 90.72% of the output value, so we can write it down as x=90.72%.
5. Now we have two simple equations:
1) 129.7=100%
2) x=90.72%
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:
129.7/x=100%/90.72%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 90.72% of 129.7

129.7/x=100/90.72
(129.7/x)*x=(100/90.72)*x       - we multiply both sides of the equation by x
129.7=1.1022927689594*x       - we divide both sides of the equation by (1.1022927689594) to get x
129.7/1.1022927689594=x
117.66384=x
x=117.66384

now we have:
90.72% of 129.7=117.66384
