3.21 is what percent of 15.92 - 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 15.92 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 15.92, so we can write it down as 100%=15.92.
4. We know, that x% equals 3.21 of the output value, so we can write it down as x%=3.21.
5. Now we have two simple equations:
1) 100%=15.92
2) x%=3.21
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%=15.92/3.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.21 is what percent of 15.92

100%/x%=15.92/3.21
(100/x)*x=(15.92/3.21)*x       - we multiply both sides of the equation by x
100=4.9595015576324*x       - we divide both sides of the equation by (4.9595015576324) to get x
100/4.9595015576324=x
20.163316582915=x
x=20.163316582915

now we have:
3.21 is 20.163316582915% of 15.92
