38 is what percent of 25.8 - 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 25.8 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 25.8, so we can write it down as 100%=25.8.
4. We know, that x% equals 38 of the output value, so we can write it down as x%=38.
5. Now we have two simple equations:
1) 100%=25.8
2) x%=38
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%=25.8/38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38 is what percent of 25.8

100%/x%=25.8/38
(100/x)*x=(25.8/38)*x       - we multiply both sides of the equation by x
100=0.67894736842105*x       - we divide both sides of the equation by (0.67894736842105) to get x
100/0.67894736842105=x
147.28682170543=x
x=147.28682170543

now we have:
38 is 147.28682170543% of 25.8
