What is 3.12 percent of 5.49 - 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 5.49 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 5.49 is 100%, so we can write it down as 5.49=100%.
4. We know, that x is 3.12% of the output value, so we can write it down as x=3.12%.
5. Now we have two simple equations:
1) 5.49=100%
2) x=3.12%
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:
5.49/x=100%/3.12%
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 3.12% of 5.49

5.49/x=100/3.12
(5.49/x)*x=(100/3.12)*x       - we multiply both sides of the equation by x
5.49=32.051282051282*x       - we divide both sides of the equation by (32.051282051282) to get x
5.49/32.051282051282=x
0.171288=x
x=0.171288

now we have:
3.12% of 5.49=0.171288
