What is 0.478 percent of 630 - 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 630 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 630 is 100%, so we can write it down as 630=100%.
4. We know, that x is 0.478% of the output value, so we can write it down as x=0.478%.
5. Now we have two simple equations:
1) 630=100%
2) x=0.478%
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:
630/x=100%/0.478%
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 0.478% of 630

630/x=100/0.478
(630/x)*x=(100/0.478)*x       - we multiply both sides of the equation by x
630=209.2050209205*x       - we divide both sides of the equation by (209.2050209205) to get x
630/209.2050209205=x
3.0114=x
x=3.0114

now we have:
0.478% of 630=3.0114
