0.89 is what percent of 142.5 - 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 142.5 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 142.5, so we can write it down as 100%=142.5.
4. We know, that x% equals 0.89 of the output value, so we can write it down as x%=0.89.
5. Now we have two simple equations:
1) 100%=142.5
2) x%=0.89
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%=142.5/0.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.89 is what percent of 142.5

100%/x%=142.5/0.89
(100/x)*x=(142.5/0.89)*x       - we multiply both sides of the equation by x
100=160.11235955056*x       - we divide both sides of the equation by (160.11235955056) to get x
100/160.11235955056=x
0.62456140350877=x
x=0.62456140350877

now we have:
0.89 is 0.62456140350877% of 142.5
