21 is what percent of 4141 - 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 4141 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 4141, so we can write it down as 100%=4141.
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%=4141
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%=4141/21
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 4141

100%/x%=4141/21
(100/x)*x=(4141/21)*x       - we multiply both sides of the equation by x
100=197.19047619048*x       - we divide both sides of the equation by (197.19047619048) to get x
100/197.19047619048=x
0.50712388312002=x
x=0.50712388312002

now we have:
21 is 0.50712388312002% of 4141
