28.5 is what percent of 27 - 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 27 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 27, so we can write it down as 100%=27.
4. We know, that x% equals 28.5 of the output value, so we can write it down as x%=28.5.
5. Now we have two simple equations:
1) 100%=27
2) x%=28.5
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%=27/28.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.5 is what percent of 27

100%/x%=27/28.5
(100/x)*x=(27/28.5)*x       - we multiply both sides of the equation by x
100=0.94736842105263*x       - we divide both sides of the equation by (0.94736842105263) to get x
100/0.94736842105263=x
105.55555555556=x
x=105.55555555556

now we have:
28.5 is 105.55555555556% of 27
