What is 9 percent of 3.442 - 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 3.442 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 3.442 is 100%, so we can write it down as 3.442=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) 3.442=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:
3.442/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 3.442

3.442/x=100/9
(3.442/x)*x=(100/9)*x       - we multiply both sides of the equation by x
3.442=11.111111111111*x       - we divide both sides of the equation by (11.111111111111) to get x
3.442/11.111111111111=x
0.30978=x
x=0.30978

now we have:
9% of 3.442=0.30978
