11.8 is what percent of 2.5 - 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 2.5 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 2.5, so we can write it down as 100%=2.5.
4. We know, that x% equals 11.8 of the output value, so we can write it down as x%=11.8.
5. Now we have two simple equations:
1) 100%=2.5
2) x%=11.8
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%=2.5/11.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.8 is what percent of 2.5

100%/x%=2.5/11.8
(100/x)*x=(2.5/11.8)*x       - we multiply both sides of the equation by x
100=0.21186440677966*x       - we divide both sides of the equation by (0.21186440677966) to get x
100/0.21186440677966=x
472=x
x=472

now we have:
11.8 is 472% of 2.5
