25 is what percent of 70.57 - 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 70.57 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 70.57, so we can write it down as 100%=70.57.
4. We know, that x% equals 25 of the output value, so we can write it down as x%=25.
5. Now we have two simple equations:
1) 100%=70.57
2) x%=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%=70.57/25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25 is what percent of 70.57

100%/x%=70.57/25
(100/x)*x=(70.57/25)*x       - we multiply both sides of the equation by x
100=2.8228*x       - we divide both sides of the equation by (2.8228) to get x
100/2.8228=x
35.425818336404=x
x=35.425818336404

now we have:
25 is 35.425818336404% of 70.57
