25 is what percent of 915.75 - 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 915.75 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 915.75, so we can write it down as 100%=915.75.
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%=915.75
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%=915.75/25
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 915.75

100%/x%=915.75/25
(100/x)*x=(915.75/25)*x       - we multiply both sides of the equation by x
100=36.63*x       - we divide both sides of the equation by (36.63) to get x
100/36.63=x
2.7300027300027=x
x=2.7300027300027

now we have:
25 is 2.7300027300027% of 915.75
