191.5 is what percent of 490.5 - 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 490.5 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 490.5, so we can write it down as 100%=490.5.
4. We know, that x% equals 191.5 of the output value, so we can write it down as x%=191.5.
5. Now we have two simple equations:
1) 100%=490.5
2) x%=191.5
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%=490.5/191.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 191.5 is what percent of 490.5

100%/x%=490.5/191.5
(100/x)*x=(490.5/191.5)*x       - we multiply both sides of the equation by x
100=2.5613577023499*x       - we divide both sides of the equation by (2.5613577023499) to get x
100/2.5613577023499=x
39.041794087666=x
x=39.041794087666

now we have:
191.5 is 39.041794087666% of 490.5
