21.37 is what percent of 613 - 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 613 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 613, so we can write it down as 100%=613.
4. We know, that x% equals 21.37 of the output value, so we can write it down as x%=21.37.
5. Now we have two simple equations:
1) 100%=613
2) x%=21.37
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%=613/21.37
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.37 is what percent of 613

100%/x%=613/21.37
(100/x)*x=(613/21.37)*x       - we multiply both sides of the equation by x
100=28.685072531586*x       - we divide both sides of the equation by (28.685072531586) to get x
100/28.685072531586=x
3.4861337683524=x
x=3.4861337683524

now we have:
21.37 is 3.4861337683524% of 613
