20 is what percent of 114.8 - 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 114.8 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 114.8, so we can write it down as 100%=114.8.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=114.8
2) x%=20
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%=114.8/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 114.8

100%/x%=114.8/20
(100/x)*x=(114.8/20)*x       - we multiply both sides of the equation by x
100=5.74*x       - we divide both sides of the equation by (5.74) to get x
100/5.74=x
17.421602787456=x
x=17.421602787456

now we have:
20 is 17.421602787456% of 114.8
