What is 0.1 percent of 427 - 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 427 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 427 is 100%, so we can write it down as 427=100%.
4. We know, that x is 0.1% of the output value, so we can write it down as x=0.1%.
5. Now we have two simple equations:
1) 427=100%
2) x=0.1%
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:
427/x=100%/0.1%
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 0.1% of 427

427/x=100/0.1
(427/x)*x=(100/0.1)*x       - we multiply both sides of the equation by x
427=1000*x       - we divide both sides of the equation by (1000) to get x
427/1000=x
0.427=x
x=0.427

now we have:
0.1% of 427=0.427
