25 is what percent of 62.9 - 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 62.9 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 62.9, so we can write it down as 100%=62.9.
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%=62.9
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%=62.9/25
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 62.9

100%/x%=62.9/25
(100/x)*x=(62.9/25)*x       - we multiply both sides of the equation by x
100=2.516*x       - we divide both sides of the equation by (2.516) to get x
100/2.516=x
39.745627980922=x
x=39.745627980922

now we have:
25 is 39.745627980922% of 62.9
