210.32 is what percent of 1045 - 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 1045 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 1045, so we can write it down as 100%=1045.
4. We know, that x% equals 210.32 of the output value, so we can write it down as x%=210.32.
5. Now we have two simple equations:
1) 100%=1045
2) x%=210.32
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%=1045/210.32
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 210.32 is what percent of 1045

100%/x%=1045/210.32
(100/x)*x=(1045/210.32)*x       - we multiply both sides of the equation by x
100=4.9686192468619*x       - we divide both sides of the equation by (4.9686192468619) to get x
100/4.9686192468619=x
20.126315789474=x
x=20.126315789474

now we have:
210.32 is 20.126315789474% of 1045
