What is 62.5 percent of 1280 - 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 1280 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 1280 is 100%, so we can write it down as 1280=100%.
4. We know, that x is 62.5% of the output value, so we can write it down as x=62.5%.
5. Now we have two simple equations:
1) 1280=100%
2) x=62.5%
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:
1280/x=100%/62.5%
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 62.5% of 1280

1280/x=100/62.5
(1280/x)*x=(100/62.5)*x       - we multiply both sides of the equation by x
1280=1.6*x       - we divide both sides of the equation by (1.6) to get x
1280/1.6=x
800=x
x=800

now we have:
62.5% of 1280=800
