27.5 is what percent of 287.75 - 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 287.75 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 287.75, so we can write it down as 100%=287.75.
4. We know, that x% equals 27.5 of the output value, so we can write it down as x%=27.5.
5. Now we have two simple equations:
1) 100%=287.75
2) x%=27.5
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%=287.75/27.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.5 is what percent of 287.75

100%/x%=287.75/27.5
(100/x)*x=(287.75/27.5)*x       - we multiply both sides of the equation by x
100=10.463636363636*x       - we divide both sides of the equation by (10.463636363636) to get x
100/10.463636363636=x
9.5569070373588=x
x=9.5569070373588

now we have:
27.5 is 9.5569070373588% of 287.75
