32 is what percent of 39.9 - 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 39.9 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 39.9, so we can write it down as 100%=39.9.
4. We know, that x% equals 32 of the output value, so we can write it down as x%=32.
5. Now we have two simple equations:
1) 100%=39.9
2) x%=32
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%=39.9/32
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 32 is what percent of 39.9

100%/x%=39.9/32
(100/x)*x=(39.9/32)*x       - we multiply both sides of the equation by x
100=1.246875*x       - we divide both sides of the equation by (1.246875) to get x
100/1.246875=x
80.200501253133=x
x=80.200501253133

now we have:
32 is 80.200501253133% of 39.9
