263.4 is what percent of 289.2 - 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 289.2 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 289.2, so we can write it down as 100%=289.2.
4. We know, that x% equals 263.4 of the output value, so we can write it down as x%=263.4.
5. Now we have two simple equations:
1) 100%=289.2
2) x%=263.4
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%=289.2/263.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 263.4 is what percent of 289.2

100%/x%=289.2/263.4
(100/x)*x=(289.2/263.4)*x       - we multiply both sides of the equation by x
100=1.0979498861048*x       - we divide both sides of the equation by (1.0979498861048) to get x
100/1.0979498861048=x
91.078838174274=x
x=91.078838174274

now we have:
263.4 is 91.078838174274% of 289.2
