What is 0.225 percent of 300 - 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 300 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 300 is 100%, so we can write it down as 300=100%.
4. We know, that x is 0.225% of the output value, so we can write it down as x=0.225%.
5. Now we have two simple equations:
1) 300=100%
2) x=0.225%
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:
300/x=100%/0.225%
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 0.225% of 300

300/x=100/0.225
(300/x)*x=(100/0.225)*x       - we multiply both sides of the equation by x
300=444.44444444444*x       - we divide both sides of the equation by (444.44444444444) to get x
300/444.44444444444=x
0.675=x
x=0.675

now we have:
0.225% of 300=0.675
