0.14 is what percent of 40 - 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 40 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 40, so we can write it down as 100%=40.
4. We know, that x% equals 0.14 of the output value, so we can write it down as x%=0.14.
5. Now we have two simple equations:
1) 100%=40
2) x%=0.14
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%=40/0.14
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.14 is what percent of 40

100%/x%=40/0.14
(100/x)*x=(40/0.14)*x       - we multiply both sides of the equation by x
100=285.71428571429*x       - we divide both sides of the equation by (285.71428571429) to get x
100/285.71428571429=x
0.35=x
x=0.35

now we have:
0.14 is 0.35% of 40
