84 is what percent of 140.5 - 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 140.5 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 140.5, so we can write it down as 100%=140.5.
4. We know, that x% equals 84 of the output value, so we can write it down as x%=84.
5. Now we have two simple equations:
1) 100%=140.5
2) x%=84
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%=140.5/84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 84 is what percent of 140.5

100%/x%=140.5/84
(100/x)*x=(140.5/84)*x       - we multiply both sides of the equation by x
100=1.672619047619*x       - we divide both sides of the equation by (1.672619047619) to get x
100/1.672619047619=x
59.786476868327=x
x=59.786476868327

now we have:
84 is 59.786476868327% of 140.5
