What is 9.9 percent of 23456789 - 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 23456789 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 23456789 is 100%, so we can write it down as 23456789=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) 23456789=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:
23456789/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 23456789

23456789/x=100/9.9
(23456789/x)*x=(100/9.9)*x       - we multiply both sides of the equation by x
23456789=10.101010101*x       - we divide both sides of the equation by (10.101010101) to get x
23456789/10.101010101=x
2322222.111=x
x=2322222.111

now we have:
9.9% of 23456789=2322222.111
