What is 0.09 percent of 993 - 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 993 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 993 is 100%, so we can write it down as 993=100%.
4. We know, that x is 0.09% of the output value, so we can write it down as x=0.09%.
5. Now we have two simple equations:
1) 993=100%
2) x=0.09%
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:
993/x=100%/0.09%
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 0.09% of 993

993/x=100/0.09
(993/x)*x=(100/0.09)*x       - we multiply both sides of the equation by x
993=1111.1111111111*x       - we divide both sides of the equation by (1111.1111111111) to get x
993/1111.1111111111=x
0.8937=x
x=0.8937

now we have:
0.09% of 993=0.8937
