21.15 is what percent of 120000 - 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 120000 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 120000, so we can write it down as 100%=120000.
4. We know, that x% equals 21.15 of the output value, so we can write it down as x%=21.15.
5. Now we have two simple equations:
1) 100%=120000
2) x%=21.15
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%=120000/21.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.15 is what percent of 120000

100%/x%=120000/21.15
(100/x)*x=(120000/21.15)*x       - we multiply both sides of the equation by x
100=5673.7588652482*x       - we divide both sides of the equation by (5673.7588652482) to get x
100/5673.7588652482=x
0.017625=x
x=0.017625

now we have:
21.15 is 0.017625% of 120000
