What is 0.1 percent of 53.1 - 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 53.1 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 53.1 is 100%, so we can write it down as 53.1=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) 53.1=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:
53.1/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 53.1

53.1/x=100/0.1
(53.1/x)*x=(100/0.1)*x       - we multiply both sides of the equation by x
53.1=1000*x       - we divide both sides of the equation by (1000) to get x
53.1/1000=x
0.0531=x
x=0.0531

now we have:
0.1% of 53.1=0.0531
