128.42 is what percent of 190 - 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 190 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 190, so we can write it down as 100%=190.
4. We know, that x% equals 128.42 of the output value, so we can write it down as x%=128.42.
5. Now we have two simple equations:
1) 100%=190
2) x%=128.42
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%=190/128.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.42 is what percent of 190

100%/x%=190/128.42
(100/x)*x=(190/128.42)*x       - we multiply both sides of the equation by x
100=1.4795203239371*x       - we divide both sides of the equation by (1.4795203239371) to get x
100/1.4795203239371=x
67.589473684211=x
x=67.589473684211

now we have:
128.42 is 67.589473684211% of 190
