What is 3.18 percent of 900 - 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 900 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 900 is 100%, so we can write it down as 900=100%.
4. We know, that x is 3.18% of the output value, so we can write it down as x=3.18%.
5. Now we have two simple equations:
1) 900=100%
2) x=3.18%
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:
900/x=100%/3.18%
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 3.18% of 900

900/x=100/3.18
(900/x)*x=(100/3.18)*x       - we multiply both sides of the equation by x
900=31.446540880503*x       - we divide both sides of the equation by (31.446540880503) to get x
900/31.446540880503=x
28.62=x
x=28.62

now we have:
3.18% of 900=28.62
