142.5 is what percent of 219.1 - 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 219.1 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 219.1, so we can write it down as 100%=219.1.
4. We know, that x% equals 142.5 of the output value, so we can write it down as x%=142.5.
5. Now we have two simple equations:
1) 100%=219.1
2) x%=142.5
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%=219.1/142.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 142.5 is what percent of 219.1

100%/x%=219.1/142.5
(100/x)*x=(219.1/142.5)*x       - we multiply both sides of the equation by x
100=1.5375438596491*x       - we divide both sides of the equation by (1.5375438596491) to get x
100/1.5375438596491=x
65.038795070744=x
x=65.038795070744

now we have:
142.5 is 65.038795070744% of 219.1
