276.87 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 276.87 of the output value, so we can write it down as x%=276.87.
5. Now we have two simple equations:
1) 100%=305
2) x%=276.87
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%=305/276.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 276.87 is what percent of 305

100%/x%=305/276.87
(100/x)*x=(305/276.87)*x       - we multiply both sides of the equation by x
100=1.1016000288944*x       - we divide both sides of the equation by (1.1016000288944) to get x
100/1.1016000288944=x
90.777049180328=x
x=90.777049180328

now we have:
276.87 is 90.777049180328% of 305
