4.25 is what percent of 5.2 - 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 5.2 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 5.2, so we can write it down as 100%=5.2.
4. We know, that x% equals 4.25 of the output value, so we can write it down as x%=4.25.
5. Now we have two simple equations:
1) 100%=5.2
2) x%=4.25
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%=5.2/4.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.25 is what percent of 5.2

100%/x%=5.2/4.25
(100/x)*x=(5.2/4.25)*x       - we multiply both sides of the equation by x
100=1.2235294117647*x       - we divide both sides of the equation by (1.2235294117647) to get x
100/1.2235294117647=x
81.730769230769=x
x=81.730769230769

now we have:
4.25 is 81.730769230769% of 5.2
