25.99 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 25.99 of the output value, so we can write it down as x%=25.99.
5. Now we have two simple equations:
1) 100%=489
2) x%=25.99
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%=489/25.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.99 is what percent of 489

100%/x%=489/25.99
(100/x)*x=(489/25.99)*x       - we multiply both sides of the equation by x
100=18.814928818776*x       - we divide both sides of the equation by (18.814928818776) to get x
100/18.814928818776=x
5.3149284253579=x
x=5.3149284253579

now we have:
25.99 is 5.3149284253579% of 489
