39.54 is what percent of 290 - 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 290 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 290, so we can write it down as 100%=290.
4. We know, that x% equals 39.54 of the output value, so we can write it down as x%=39.54.
5. Now we have two simple equations:
1) 100%=290
2) x%=39.54
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%=290/39.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.54 is what percent of 290

100%/x%=290/39.54
(100/x)*x=(290/39.54)*x       - we multiply both sides of the equation by x
100=7.3343449671219*x       - we divide both sides of the equation by (7.3343449671219) to get x
100/7.3343449671219=x
13.634482758621=x
x=13.634482758621

now we have:
39.54 is 13.634482758621% of 290
