21 is what percent of 35.188 - 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 35.188 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 35.188, so we can write it down as 100%=35.188.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=35.188
2) x%=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%=35.188/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21 is what percent of 35.188

100%/x%=35.188/21
(100/x)*x=(35.188/21)*x       - we multiply both sides of the equation by x
100=1.675619047619*x       - we divide both sides of the equation by (1.675619047619) to get x
100/1.675619047619=x
59.679436171422=x
x=59.679436171422

now we have:
21 is 59.679436171422% of 35.188
