25.8 is what percent of 42.99 - 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 42.99 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 42.99, so we can write it down as 100%=42.99.
4. We know, that x% equals 25.8 of the output value, so we can write it down as x%=25.8.
5. Now we have two simple equations:
1) 100%=42.99
2) x%=25.8
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%=42.99/25.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.8 is what percent of 42.99

100%/x%=42.99/25.8
(100/x)*x=(42.99/25.8)*x       - we multiply both sides of the equation by x
100=1.6662790697674*x       - we divide both sides of the equation by (1.6662790697674) to get x
100/1.6662790697674=x
60.013956734124=x
x=60.013956734124

now we have:
25.8 is 60.013956734124% of 42.99
