What is 7.75 percent of 15978 - 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 15978 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 15978 is 100%, so we can write it down as 15978=100%.
4. We know, that x is 7.75% of the output value, so we can write it down as x=7.75%.
5. Now we have two simple equations:
1) 15978=100%
2) x=7.75%
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:
15978/x=100%/7.75%
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 7.75% of 15978

15978/x=100/7.75
(15978/x)*x=(100/7.75)*x       - we multiply both sides of the equation by x
15978=12.903225806452*x       - we divide both sides of the equation by (12.903225806452) to get x
15978/12.903225806452=x
1238.295=x
x=1238.295

now we have:
7.75% of 15978=1238.295
