305.4 is what percent of 337.5 - 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 337.5 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 337.5, so we can write it down as 100%=337.5.
4. We know, that x% equals 305.4 of the output value, so we can write it down as x%=305.4.
5. Now we have two simple equations:
1) 100%=337.5
2) x%=305.4
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%=337.5/305.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 305.4 is what percent of 337.5

100%/x%=337.5/305.4
(100/x)*x=(337.5/305.4)*x       - we multiply both sides of the equation by x
100=1.1051080550098*x       - we divide both sides of the equation by (1.1051080550098) to get x
100/1.1051080550098=x
90.488888888889=x
x=90.488888888889

now we have:
305.4 is 90.488888888889% of 337.5
