11.25 is what percent of 15.57 - 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 15.57 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 15.57, so we can write it down as 100%=15.57.
4. We know, that x% equals 11.25 of the output value, so we can write it down as x%=11.25.
5. Now we have two simple equations:
1) 100%=15.57
2) x%=11.25
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%=15.57/11.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.25 is what percent of 15.57

100%/x%=15.57/11.25
(100/x)*x=(15.57/11.25)*x       - we multiply both sides of the equation by x
100=1.384*x       - we divide both sides of the equation by (1.384) to get x
100/1.384=x
72.254335260116=x
x=72.254335260116

now we have:
11.25 is 72.254335260116% of 15.57
