What is 28.8 percent of 1440 - 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 1440 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 1440 is 100%, so we can write it down as 1440=100%.
4. We know, that x is 28.8% of the output value, so we can write it down as x=28.8%.
5. Now we have two simple equations:
1) 1440=100%
2) x=28.8%
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:
1440/x=100%/28.8%
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 28.8% of 1440

1440/x=100/28.8
(1440/x)*x=(100/28.8)*x       - we multiply both sides of the equation by x
1440=3.4722222222222*x       - we divide both sides of the equation by (3.4722222222222) to get x
1440/3.4722222222222=x
414.72=x
x=414.72

now we have:
28.8% of 1440=414.72
