275.35 is what percent of 305 - 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 305 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 305, so we can write it down as 100%=305.
4. We know, that x% equals 275.35 of the output value, so we can write it down as x%=275.35.
5. Now we have two simple equations:
1) 100%=305
2) x%=275.35
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%=305/275.35
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 275.35 is what percent of 305

100%/x%=305/275.35
(100/x)*x=(305/275.35)*x       - we multiply both sides of the equation by x
100=1.1076811331033*x       - we divide both sides of the equation by (1.1076811331033) to get x
100/1.1076811331033=x
90.27868852459=x
x=90.27868852459

now we have:
275.35 is 90.27868852459% of 305
