Alrighty, so if I recall correctly you first need to convert 1/6 into a number that has the same denominator as 1/12. Multiply 1/6 by 2 in the numerator and denominator: 12=2, 62=12. Your new fraction is 2/12. 1/12+2/12=3/12. 3/12 of the pot has been eaten. 12/12 makes a whole pot so you subtract 12-3 and you get 9/12 of the pot that has not been eaten yet. 9/12 simplified is 3/4. Hope this helps.
