289.5 is what percent of 299.9 - 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 299.9 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 299.9, so we can write it down as 100%=299.9.
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%=299.9
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%=299.9/289.5
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 299.9

100%/x%=299.9/289.5
(100/x)*x=(299.9/289.5)*x       - we multiply both sides of the equation by x
100=1.0359240069085*x       - we divide both sides of the equation by (1.0359240069085) to get x
100/1.0359240069085=x
96.532177392464=x
x=96.532177392464

now we have:
289.5 is 96.532177392464% of 299.9
