What is 25 percent of 17.85 - 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 17.85 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 17.85 is 100%, so we can write it down as 17.85=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) 17.85=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:
17.85/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 17.85

17.85/x=100/25
(17.85/x)*x=(100/25)*x       - we multiply both sides of the equation by x
17.85=4*x       - we divide both sides of the equation by (4) to get x
17.85/4=x
4.4625=x
x=4.4625

now we have:
25% of 17.85=4.4625
