43.6 is what percent of 489 - 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 489 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 489, so we can write it down as 100%=489.
4. We know, that x% equals 43.6 of the output value, so we can write it down as x%=43.6.
5. Now we have two simple equations:
1) 100%=489
2) x%=43.6
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%=489/43.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.6 is what percent of 489

100%/x%=489/43.6
(100/x)*x=(489/43.6)*x       - we multiply both sides of the equation by x
100=11.215596330275*x       - we divide both sides of the equation by (11.215596330275) to get x
100/11.215596330275=x
8.9161554192229=x
x=8.9161554192229

now we have:
43.6 is 8.9161554192229% of 489
