67.21 is what percent of 335.52 - 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 335.52 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 335.52, so we can write it down as 100%=335.52.
4. We know, that x% equals 67.21 of the output value, so we can write it down as x%=67.21.
5. Now we have two simple equations:
1) 100%=335.52
2) x%=67.21
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%=335.52/67.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 67.21 is what percent of 335.52

100%/x%=335.52/67.21
(100/x)*x=(335.52/67.21)*x       - we multiply both sides of the equation by x
100=4.99211426871*x       - we divide both sides of the equation by (4.99211426871) to get x
100/4.99211426871=x
20.03159275155=x
x=20.03159275155

now we have:
67.21 is 20.03159275155% of 335.52
