389.3 is what percent of 499 - 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 499 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 499, so we can write it down as 100%=499.
4. We know, that x% equals 389.3 of the output value, so we can write it down as x%=389.3.
5. Now we have two simple equations:
1) 100%=499
2) x%=389.3
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%=499/389.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 389.3 is what percent of 499

100%/x%=499/389.3
(100/x)*x=(499/389.3)*x       - we multiply both sides of the equation by x
100=1.2817878243*x       - we divide both sides of the equation by (1.2817878243) to get x
100/1.2817878243=x
78.016032064128=x
x=78.016032064128

now we have:
389.3 is 78.016032064128% of 499
