What is 9.9 percent of 6.75 - 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 6.75 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 6.75 is 100%, so we can write it down as 6.75=100%.
4. We know, that x is 9.9% of the output value, so we can write it down as x=9.9%.
5. Now we have two simple equations:
1) 6.75=100%
2) x=9.9%
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:
6.75/x=100%/9.9%
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 9.9% of 6.75

6.75/x=100/9.9
(6.75/x)*x=(100/9.9)*x       - we multiply both sides of the equation by x
6.75=10.101010101*x       - we divide both sides of the equation by (10.101010101) to get x
6.75/10.101010101=x
0.66825=x
x=0.66825

now we have:
9.9% of 6.75=0.66825
