21 is what percent of 88.23 - 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 88.23 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 88.23, so we can write it down as 100%=88.23.
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%=88.23
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%=88.23/21
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 88.23

100%/x%=88.23/21
(100/x)*x=(88.23/21)*x       - we multiply both sides of the equation by x
100=4.2014285714286*x       - we divide both sides of the equation by (4.2014285714286) to get x
100/4.2014285714286=x
23.801428085685=x
x=23.801428085685

now we have:
21 is 23.801428085685% of 88.23
