67.5 is what percent of 98.1 - 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 98.1 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 98.1, so we can write it down as 100%=98.1.
4. We know, that x% equals 67.5 of the output value, so we can write it down as x%=67.5.
5. Now we have two simple equations:
1) 100%=98.1
2) x%=67.5
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%=98.1/67.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 67.5 is what percent of 98.1

100%/x%=98.1/67.5
(100/x)*x=(98.1/67.5)*x       - we multiply both sides of the equation by x
100=1.4533333333333*x       - we divide both sides of the equation by (1.4533333333333) to get x
100/1.4533333333333=x
68.807339449541=x
x=68.807339449541

now we have:
67.5 is 68.807339449541% of 98.1
