What is 25 percent of 514.28 - 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 514.28 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 514.28 is 100%, so we can write it down as 514.28=100%.
4. We know, that x is 25% of the output value, so we can write it down as x=25%.
5. Now we have two simple equations:
1) 514.28=100%
2) x=25%
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:
514.28/x=100%/25%
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 25% of 514.28

514.28/x=100/25
(514.28/x)*x=(100/25)*x       - we multiply both sides of the equation by x
514.28=4*x       - we divide both sides of the equation by (4) to get x
514.28/4=x
128.57=x
x=128.57

now we have:
25% of 514.28=128.57
