0.15 is what percent of 140 - 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 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, so we can write it down as 100%=140.
4. We know, that x% equals 0.15 of the output value, so we can write it down as x%=0.15.
5. Now we have two simple equations:
1) 100%=140
2) x%=0.15
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%=140/0.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.15 is what percent of 140

100%/x%=140/0.15
(100/x)*x=(140/0.15)*x       - we multiply both sides of the equation by x
100=933.33333333333*x       - we divide both sides of the equation by (933.33333333333) to get x
100/933.33333333333=x
0.10714285714286=x
x=0.10714285714286

now we have:
0.15 is 0.10714285714286% of 140
