31.93 is what percent of 39.95 - 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 39.95 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 39.95, so we can write it down as 100%=39.95.
4. We know, that x% equals 31.93 of the output value, so we can write it down as x%=31.93.
5. Now we have two simple equations:
1) 100%=39.95
2) x%=31.93
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%=39.95/31.93
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.93 is what percent of 39.95

100%/x%=39.95/31.93
(100/x)*x=(39.95/31.93)*x       - we multiply both sides of the equation by x
100=1.2511744440965*x       - we divide both sides of the equation by (1.2511744440965) to get x
100/1.2511744440965=x
79.924906132666=x
x=79.924906132666

now we have:
31.93 is 79.924906132666% of 39.95
