What is 3.2 percent of 124 - 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 124 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 124 is 100%, so we can write it down as 124=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) 124=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:
124/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 124

124/x=100/3.2
(124/x)*x=(100/3.2)*x       - we multiply both sides of the equation by x
124=31.25*x       - we divide both sides of the equation by (31.25) to get x
124/31.25=x
3.968=x
x=3.968

now we have:
3.2% of 124=3.968
