What is 0.25 percent of 3550 - 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 3550 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 3550 is 100%, so we can write it down as 3550=100%.
4. We know, that x is 0.25% of the output value, so we can write it down as x=0.25%.
5. Now we have two simple equations:
1) 3550=100%
2) x=0.25%
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:
3550/x=100%/0.25%
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 0.25% of 3550

3550/x=100/0.25
(3550/x)*x=(100/0.25)*x       - we multiply both sides of the equation by x
3550=400*x       - we divide both sides of the equation by (400) to get x
3550/400=x
8.875=x
x=8.875

now we have:
0.25% of 3550=8.875
