22.9 is what percent of 47.8 - 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 47.8 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 47.8, so we can write it down as 100%=47.8.
4. We know, that x% equals 22.9 of the output value, so we can write it down as x%=22.9.
5. Now we have two simple equations:
1) 100%=47.8
2) x%=22.9
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%=47.8/22.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22.9 is what percent of 47.8

100%/x%=47.8/22.9
(100/x)*x=(47.8/22.9)*x       - we multiply both sides of the equation by x
100=2.0873362445415*x       - we divide both sides of the equation by (2.0873362445415) to get x
100/2.0873362445415=x
47.907949790795=x
x=47.907949790795

now we have:
22.9 is 47.907949790795% of 47.8
