21 is what percent of 24.19 - 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 24.19 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 24.19, so we can write it down as 100%=24.19.
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%=24.19
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%=24.19/21
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 24.19

100%/x%=24.19/21
(100/x)*x=(24.19/21)*x       - we multiply both sides of the equation by x
100=1.1519047619048*x       - we divide both sides of the equation by (1.1519047619048) to get x
100/1.1519047619048=x
86.812732534105=x
x=86.812732534105

now we have:
21 is 86.812732534105% of 24.19
