What is 25 percent of 30.784 - 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 30.784 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 30.784 is 100%, so we can write it down as 30.784=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) 30.784=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:
30.784/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 30.784

30.784/x=100/25
(30.784/x)*x=(100/25)*x       - we multiply both sides of the equation by x
30.784=4*x       - we divide both sides of the equation by (4) to get x
30.784/4=x
7.696=x
x=7.696

now we have:
25% of 30.784=7.696
