319.5 is what percent of 354.5 - 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 354.5 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 354.5, so we can write it down as 100%=354.5.
4. We know, that x% equals 319.5 of the output value, so we can write it down as x%=319.5.
5. Now we have two simple equations:
1) 100%=354.5
2) x%=319.5
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%=354.5/319.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 319.5 is what percent of 354.5

100%/x%=354.5/319.5
(100/x)*x=(354.5/319.5)*x       - we multiply both sides of the equation by x
100=1.1095461658842*x       - we divide both sides of the equation by (1.1095461658842) to get x
100/1.1095461658842=x
90.126939351199=x
x=90.126939351199

now we have:
319.5 is 90.126939351199% of 354.5
