What is 39.5 percent of 48 - 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 48 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 48 is 100%, so we can write it down as 48=100%.
4. We know, that x is 39.5% of the output value, so we can write it down as x=39.5%.
5. Now we have two simple equations:
1) 48=100%
2) x=39.5%
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:
48/x=100%/39.5%
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 39.5% of 48

48/x=100/39.5
(48/x)*x=(100/39.5)*x       - we multiply both sides of the equation by x
48=2.5316455696203*x       - we divide both sides of the equation by (2.5316455696203) to get x
48/2.5316455696203=x
18.96=x
x=18.96

now we have:
39.5% of 48=18.96
