To get 11 you'd probably have to forget everything you ever learned about fractions. Seriously, though, 1/3 of 12 is 4, and 3/5 of 7 is 4.2, so when you add them you should get 8.2 (or 41/5, or 8 1/5). 11 is way off.

5 and 2 ninths is 23 ninths. 2 and 2 fifths is 12 fifths. multiply the denominator and the numerator and then add the whole number over the denominator.
To find out how many fifths are in two and two-fifths, we first need to convert the whole number, two, into fifths. Since one whole is equal to five fifths, two wholes would be equal to ten fifths. Adding the two-fifths gives us a total of twelve fifths in two and two-fifths.

The numbers are -1 and -11 because -1 times -11 = 11 and (-1)+(-11) = -12
