60 is what percent of 21100 - 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 21100 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 21100, so we can write it down as 100%=21100.
4. We know, that x% equals 60 of the output value, so we can write it down as x%=60.
5. Now we have two simple equations:
1) 100%=21100
2) x%=60
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%=21100/60
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 60 is what percent of 21100

100%/x%=21100/60
(100/x)*x=(21100/60)*x       - we multiply both sides of the equation by x
100=351.66666666667*x       - we divide both sides of the equation by (351.66666666667) to get x
100/351.66666666667=x
0.28436018957346=x
x=0.28436018957346

now we have:
60 is 0.28436018957346% of 21100
