197.1 is what percent of 1642.5 - 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 1642.5 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 1642.5, so we can write it down as 100%=1642.5.
4. We know, that x% equals 197.1 of the output value, so we can write it down as x%=197.1.
5. Now we have two simple equations:
1) 100%=1642.5
2) x%=197.1
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%=1642.5/197.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 197.1 is what percent of 1642.5

100%/x%=1642.5/197.1
(100/x)*x=(1642.5/197.1)*x       - we multiply both sides of the equation by x
100=8.3333333333333*x       - we divide both sides of the equation by (8.3333333333333) to get x
100/8.3333333333333=x
12=x
x=12

now we have:
197.1 is 12% of 1642.5
