141.9 is what percent of 1720 - 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 1720 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 1720, so we can write it down as 100%=1720.
4. We know, that x% equals 141.9 of the output value, so we can write it down as x%=141.9.
5. Now we have two simple equations:
1) 100%=1720
2) x%=141.9
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%=1720/141.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 141.9 is what percent of 1720

100%/x%=1720/141.9
(100/x)*x=(1720/141.9)*x       - we multiply both sides of the equation by x
100=12.121212121212*x       - we divide both sides of the equation by (12.121212121212) to get x
100/12.121212121212=x
8.25=x
x=8.25

now we have:
141.9 is 8.25% of 1720
