20 is what percent of 3231 - 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 3231 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 3231, so we can write it down as 100%=3231.
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%=3231
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%=3231/20
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 3231

100%/x%=3231/20
(100/x)*x=(3231/20)*x       - we multiply both sides of the equation by x
100=161.55*x       - we divide both sides of the equation by (161.55) to get x
100/161.55=x
0.61900340451872=x
x=0.61900340451872

now we have:
20 is 0.61900340451872% of 3231
