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.
Twelve There are 5 fifths in 1, so there are 10 fifths in 2 and add 2 to that to get 12
- 1 1/11 or -12/11

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.

Two and two thirds divided by one and three fifths = 12/3

7/12 minus 2/5 is 11/60.
1/3 / 4/5 = 5/12 Five twelfths
The numbers are -1 and -11 because -1 times -11 = 11 and (-1)+(-11) = -12
