Answer:
1 25/33
Step-by-step explanation:
to simplify, 12/11 is equal to 1 1/11.
A double negative (minus a negative) is a positive. Your equation then becomes 1 1/11+ 2/3.
Then you must find a common denominator.
1 +
you must then multiply both the numerator and denominator by the other denominator.
1 x 3 = 3
11 x 3 =33
2 x 11 = 22
3 x 11 = 33
You not add 1 3/33 and 22/33 and you have 1 25/33
