39.95 is what percent of 69.95 - 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 69.95 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 69.95, so we can write it down as 100%=69.95.
4. We know, that x% equals 39.95 of the output value, so we can write it down as x%=39.95.
5. Now we have two simple equations:
1) 100%=69.95
2) x%=39.95
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%=69.95/39.95
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.95 is what percent of 69.95

100%/x%=69.95/39.95
(100/x)*x=(69.95/39.95)*x       - we multiply both sides of the equation by x
100=1.7509386733417*x       - we divide both sides of the equation by (1.7509386733417) to get x
100/1.7509386733417=x
57.11222301644=x
x=57.11222301644

now we have:
39.95 is 57.11222301644% of 69.95
