What is 9 percent of 77200 - 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 77200 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 77200 is 100%, so we can write it down as 77200=100%.
4. We know, that x is 9% of the output value, so we can write it down as x=9%.
5. Now we have two simple equations:
1) 77200=100%
2) x=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:
77200/x=100%/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 9% of 77200

77200/x=100/9
(77200/x)*x=(100/9)*x       - we multiply both sides of the equation by x
77200=11.111111111111*x       - we divide both sides of the equation by (11.111111111111) to get x
77200/11.111111111111=x
6948=x
x=6948

now we have:
9% of 77200=6948
