47 is what percent of 52.8 - 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 52.8 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 52.8, so we can write it down as 100%=52.8.
4. We know, that x% equals 47 of the output value, so we can write it down as x%=47.
5. Now we have two simple equations:
1) 100%=52.8
2) x%=47
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%=52.8/47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 47 is what percent of 52.8

100%/x%=52.8/47
(100/x)*x=(52.8/47)*x       - we multiply both sides of the equation by x
100=1.1234042553191*x       - we divide both sides of the equation by (1.1234042553191) to get x
100/1.1234042553191=x
89.015151515152=x
x=89.015151515152

now we have:
47 is 89.015151515152% of 52.8
