289.5 is what percent of 750 - 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 750 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 750, so we can write it down as 100%=750.
4. We know, that x% equals 289.5 of the output value, so we can write it down as x%=289.5.
5. Now we have two simple equations:
1) 100%=750
2) x%=289.5
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%=750/289.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 289.5 is what percent of 750

100%/x%=750/289.5
(100/x)*x=(750/289.5)*x       - we multiply both sides of the equation by x
100=2.5906735751295*x       - we divide both sides of the equation by (2.5906735751295) to get x
100/2.5906735751295=x
38.6=x
x=38.6

now we have:
289.5 is 38.6% of 750
