25 is what percent of 7.65 - 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 7.65 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 7.65, so we can write it down as 100%=7.65.
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%=7.65
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%=7.65/25
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 7.65

100%/x%=7.65/25
(100/x)*x=(7.65/25)*x       - we multiply both sides of the equation by x
100=0.306*x       - we divide both sides of the equation by (0.306) to get x
100/0.306=x
326.79738562092=x
x=326.79738562092

now we have:
25 is 326.79738562092% of 7.65
