What is 0.035 percent of 15 - 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 15 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 15 is 100%, so we can write it down as 15=100%.
4. We know, that x is 0.035% of the output value, so we can write it down as x=0.035%.
5. Now we have two simple equations:
1) 15=100%
2) x=0.035%
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:
15/x=100%/0.035%
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 0.035% of 15

15/x=100/0.035
(15/x)*x=(100/0.035)*x       - we multiply both sides of the equation by x
15=2857.14285714*x       - we divide both sides of the equation by (2857.14285714) to get x
15/2857.14285714=x
0.00525=x
x=0.00525

now we have:
0.035% of 15=0.00525
