What is 2.5 percent of 15.16 - 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 15.16 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 15.16 is 100%, so we can write it down as 15.16=100%.
4. We know, that x is 2.5% of the output value, so we can write it down as x=2.5%.
5. Now we have two simple equations:
1) 15.16=100%
2) x=2.5%
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:
15.16/x=100%/2.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 2.5% of 15.16

15.16/x=100/2.5
(15.16/x)*x=(100/2.5)*x       - we multiply both sides of the equation by x
15.16=40*x       - we divide both sides of the equation by (40) to get x
15.16/40=x
0.379=x
x=0.379

now we have:
2.5% of 15.16=0.379
