21.24 is what percent of 63.74 - 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 63.74 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 63.74, so we can write it down as 100%=63.74.
4. We know, that x% equals 21.24 of the output value, so we can write it down as x%=21.24.
5. Now we have two simple equations:
1) 100%=63.74
2) x%=21.24
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%=63.74/21.24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.24 is what percent of 63.74

100%/x%=63.74/21.24
(100/x)*x=(63.74/21.24)*x       - we multiply both sides of the equation by x
100=3.0009416195857*x       - we divide both sides of the equation by (3.0009416195857) to get x
100/3.0009416195857=x
33.322874176341=x
x=33.322874176341

now we have:
21.24 is 33.322874176341% of 63.74
