11.43 is what percent of 90 - 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 90 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 90, so we can write it down as 100%=90.
4. We know, that x% equals 11.43 of the output value, so we can write it down as x%=11.43.
5. Now we have two simple equations:
1) 100%=90
2) x%=11.43
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%=90/11.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.43 is what percent of 90

100%/x%=90/11.43
(100/x)*x=(90/11.43)*x       - we multiply both sides of the equation by x
100=7.8740157480315*x       - we divide both sides of the equation by (7.8740157480315) to get x
100/7.8740157480315=x
12.7=x
x=12.7

now we have:
11.43 is 12.7% of 90
