157.7 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 157.7 of the output value, so we can write it down as x%=157.7.
5. Now we have two simple equations:
1) 100%=190
2) x%=157.7
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%=190/157.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 157.7 is what percent of 190

100%/x%=190/157.7
(100/x)*x=(190/157.7)*x       - we multiply both sides of the equation by x
100=1.2048192771084*x       - we divide both sides of the equation by (1.2048192771084) to get x
100/1.2048192771084=x
83=x
x=83

now we have:
157.7 is 83% of 190
