What is 15.2 percent of 18.7 - 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 18.7 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 18.7 is 100%, so we can write it down as 18.7=100%.
4. We know, that x is 15.2% of the output value, so we can write it down as x=15.2%.
5. Now we have two simple equations:
1) 18.7=100%
2) x=15.2%
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:
18.7/x=100%/15.2%
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 15.2% of 18.7

18.7/x=100/15.2
(18.7/x)*x=(100/15.2)*x       - we multiply both sides of the equation by x
18.7=6.5789473684211*x       - we divide both sides of the equation by (6.5789473684211) to get x
18.7/6.5789473684211=x
2.8424=x
x=2.8424

now we have:
15.2% of 18.7=2.8424
