20 is what percent of 32.87 - 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 32.87 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 32.87, so we can write it down as 100%=32.87.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=32.87
2) x%=20
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%=32.87/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 32.87

100%/x%=32.87/20
(100/x)*x=(32.87/20)*x       - we multiply both sides of the equation by x
100=1.6435*x       - we divide both sides of the equation by (1.6435) to get x
100/1.6435=x
60.845756008518=x
x=60.845756008518

now we have:
20 is 60.845756008518% of 32.87
