41 is what percent of 21 - 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 21 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 21, so we can write it down as 100%=21.
4. We know, that x% equals 41 of the output value, so we can write it down as x%=41.
5. Now we have two simple equations:
1) 100%=21
2) x%=41
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%=21/41
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 41 is what percent of 21

100%/x%=21/41
(100/x)*x=(21/41)*x       - we multiply both sides of the equation by x
100=0.512195121951*x       - we divide both sides of the equation by (0.512195121951) to get x
100/0.512195121951=x
195.238095238=x
x=195.238095238

now we have:
41 is 195.238095238% of 21
