What is 7.8 percent of 118 - 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 118 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 118 is 100%, so we can write it down as 118=100%.
4. We know, that x is 7.8% of the output value, so we can write it down as x=7.8%.
5. Now we have two simple equations:
1) 118=100%
2) x=7.8%
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:
118/x=100%/7.8%
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 7.8% of 118

118/x=100/7.8
(118/x)*x=(100/7.8)*x       - we multiply both sides of the equation by x
118=12.820512820513*x       - we divide both sides of the equation by (12.820512820513) to get x
118/12.820512820513=x
9.204=x
x=9.204

now we have:
7.8% of 118=9.204
