What is 3.2 percent of 168.9 - 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 168.9 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 168.9 is 100%, so we can write it down as 168.9=100%.
4. We know, that x is 3.2% of the output value, so we can write it down as x=3.2%.
5. Now we have two simple equations:
1) 168.9=100%
2) x=3.2%
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:
168.9/x=100%/3.2%
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 3.2% of 168.9

168.9/x=100/3.2
(168.9/x)*x=(100/3.2)*x       - we multiply both sides of the equation by x
168.9=31.25*x       - we divide both sides of the equation by (31.25) to get x
168.9/31.25=x
5.4048=x
x=5.4048

now we have:
3.2% of 168.9=5.4048
