25 is what percent of 7.45 - 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 7.45 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 7.45, so we can write it down as 100%=7.45.
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%=7.45
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%=7.45/25
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 7.45

100%/x%=7.45/25
(100/x)*x=(7.45/25)*x       - we multiply both sides of the equation by x
100=0.298*x       - we divide both sides of the equation by (0.298) to get x
100/0.298=x
335.57046979866=x
x=335.57046979866

now we have:
25 is 335.57046979866% of 7.45
