What is 7.8125 percent of 240 - 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 240 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 240 is 100%, so we can write it down as 240=100%.
4. We know, that x is 7.8125% of the output value, so we can write it down as x=7.8125%.
5. Now we have two simple equations:
1) 240=100%
2) x=7.8125%
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:
240/x=100%/7.8125%
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 7.8125% of 240

240/x=100/7.8125
(240/x)*x=(100/7.8125)*x       - we multiply both sides of the equation by x
240=12.8*x       - we divide both sides of the equation by (12.8) to get x
240/12.8=x
18.75=x
x=18.75

now we have:
7.8125% of 240=18.75
