300.12 is what percent of 393.6 - 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 393.6 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 393.6, so we can write it down as 100%=393.6.
4. We know, that x% equals 300.12 of the output value, so we can write it down as x%=300.12.
5. Now we have two simple equations:
1) 100%=393.6
2) x%=300.12
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%=393.6/300.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 300.12 is what percent of 393.6

100%/x%=393.6/300.12
(100/x)*x=(393.6/300.12)*x       - we multiply both sides of the equation by x
100=1.3114754098361*x       - we divide both sides of the equation by (1.3114754098361) to get x
100/1.3114754098361=x
76.25=x
x=76.25

now we have:
300.12 is 76.25% of 393.6
