141.5 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 141.5 of the output value, so we can write it down as x%=141.5.
5. Now we have two simple equations:
1) 100%=142.5
2) x%=141.5
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%=142.5/141.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 141.5 is what percent of 142.5

100%/x%=142.5/141.5
(100/x)*x=(142.5/141.5)*x       - we multiply both sides of the equation by x
100=1.0070671378092*x       - we divide both sides of the equation by (1.0070671378092) to get x
100/1.0070671378092=x
99.298245614035=x
x=99.298245614035

now we have:
141.5 is 99.298245614035% of 142.5
