42.14 is what percent of 142.14 - 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 142.14 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 142.14, so we can write it down as 100%=142.14.
4. We know, that x% equals 42.14 of the output value, so we can write it down as x%=42.14.
5. Now we have two simple equations:
1) 100%=142.14
2) x%=42.14
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%=142.14/42.14
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.14 is what percent of 142.14

100%/x%=142.14/42.14
(100/x)*x=(142.14/42.14)*x       - we multiply both sides of the equation by x
100=3.3730422401519*x       - we divide both sides of the equation by (3.3730422401519) to get x
100/3.3730422401519=x
29.646827071901=x
x=29.646827071901

now we have:
42.14 is 29.646827071901% of 142.14
