286.5 is what percent of 310 - 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 310 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 310, so we can write it down as 100%=310.
4. We know, that x% equals 286.5 of the output value, so we can write it down as x%=286.5.
5. Now we have two simple equations:
1) 100%=310
2) x%=286.5
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%=310/286.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 286.5 is what percent of 310

100%/x%=310/286.5
(100/x)*x=(310/286.5)*x       - we multiply both sides of the equation by x
100=1.0820244328098*x       - we divide both sides of the equation by (1.0820244328098) to get x
100/1.0820244328098=x
92.41935483871=x
x=92.41935483871

now we have:
286.5 is 92.41935483871% of 310
