20.74 is what percent of 25 - 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 25 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 25, so we can write it down as 100%=25.
4. We know, that x% equals 20.74 of the output value, so we can write it down as x%=20.74.
5. Now we have two simple equations:
1) 100%=25
2) x%=20.74
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%=25/20.74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.74 is what percent of 25

100%/x%=25/20.74
(100/x)*x=(25/20.74)*x       - we multiply both sides of the equation by x
100=1.205400192864*x       - we divide both sides of the equation by (1.205400192864) to get x
100/1.205400192864=x
82.96=x
x=82.96

now we have:
20.74 is 82.96% of 25
