13.15 is what percent of 901 - 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 901 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 901, so we can write it down as 100%=901.
4. We know, that x% equals 13.15 of the output value, so we can write it down as x%=13.15.
5. Now we have two simple equations:
1) 100%=901
2) x%=13.15
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%=901/13.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.15 is what percent of 901

100%/x%=901/13.15
(100/x)*x=(901/13.15)*x       - we multiply both sides of the equation by x
100=68.51711026616*x       - we divide both sides of the equation by (68.51711026616) to get x
100/68.51711026616=x
1.4594894561598=x
x=1.4594894561598

now we have:
13.15 is 1.4594894561598% of 901
