You need to find the common denominator to add and subtract fractions.
Since 10 is divisible by 5, the common denominator is 10.
9 4/5 = 9 8/10
Then add the whole numbers and the numerators.
2 3/10 + 9 8/10 = 11 11/10 = 11 1/10

Oops! I goofed in the final answer. It should be 12 1/10, not 11 1/10.
