304.69 is what percent of 387 - 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 387 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 387, so we can write it down as 100%=387.
4. We know, that x% equals 304.69 of the output value, so we can write it down as x%=304.69.
5. Now we have two simple equations:
1) 100%=387
2) x%=304.69
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%=387/304.69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 304.69 is what percent of 387

100%/x%=387/304.69
(100/x)*x=(387/304.69)*x       - we multiply both sides of the equation by x
100=1.2701434244642*x       - we divide both sides of the equation by (1.2701434244642) to get x
100/1.2701434244642=x
78.731266149871=x
x=78.731266149871

now we have:
304.69 is 78.731266149871% of 387
