4.87 is what percent of 5.25 - 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 5.25 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 5.25, so we can write it down as 100%=5.25.
4. We know, that x% equals 4.87 of the output value, so we can write it down as x%=4.87.
5. Now we have two simple equations:
1) 100%=5.25
2) x%=4.87
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%=5.25/4.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.87 is what percent of 5.25

100%/x%=5.25/4.87
(100/x)*x=(5.25/4.87)*x       - we multiply both sides of the equation by x
100=1.0780287474333*x       - we divide both sides of the equation by (1.0780287474333) to get x
100/1.0780287474333=x
92.761904761905=x
x=92.761904761905

now we have:
4.87 is 92.761904761905% of 5.25
