66.57 is what percent of 302.61 - 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 302.61 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 302.61, so we can write it down as 100%=302.61.
4. We know, that x% equals 66.57 of the output value, so we can write it down as x%=66.57.
5. Now we have two simple equations:
1) 100%=302.61
2) x%=66.57
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%=302.61/66.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.57 is what percent of 302.61

100%/x%=302.61/66.57
(100/x)*x=(302.61/66.57)*x       - we multiply both sides of the equation by x
100=4.5457413249211*x       - we divide both sides of the equation by (4.5457413249211) to get x
100/4.5457413249211=x
21.998612074948=x
x=21.998612074948

now we have:
