What is 19.9 percent of 49.5 - 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 49.5 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 49.5 is 100%, so we can write it down as 49.5=100%.
4. We know, that x is 19.9% of the output value, so we can write it down as x=19.9%.
5. Now we have two simple equations:
1) 49.5=100%
2) x=19.9%
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:
49.5/x=100%/19.9%
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 19.9% of 49.5

49.5/x=100/19.9
(49.5/x)*x=(100/19.9)*x       - we multiply both sides of the equation by x
49.5=5.0251256281407*x       - we divide both sides of the equation by (5.0251256281407) to get x
49.5/5.0251256281407=x
9.8505=x
x=9.8505

now we have:
19.9% of 49.5=9.8505
