7.65 is what percent of 25.5 - 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 25.5 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 25.5, so we can write it down as 100%=25.5.
4. We know, that x% equals 7.65 of the output value, so we can write it down as x%=7.65.
5. Now we have two simple equations:
1) 100%=25.5
2) x%=7.65
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%=25.5/7.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.65 is what percent of 25.5

100%/x%=25.5/7.65
(100/x)*x=(25.5/7.65)*x       - we multiply both sides of the equation by x
100=3.3333333333333*x       - we divide both sides of the equation by (3.3333333333333) to get x
100/3.3333333333333=x
30=x
x=30

now we have:
7.65 is 30% of 25.5
