Answer:
9/10
Step-by-step explanation:
0.9 means that 9.0×10^-1
Due the fact that the dot was shifted to the right and not to the left
9.0×10^-1
Which can also be written as
9.0/10=9/10
The two values don't have a common number that can divide them so we will leave the answer as 9/10
Therefore the mixed number of 0.9 is 9/10
