Answer:
D. 7/36 pounds
Explanation:
Combine the two using like terms so 1/3 and 1/4 = 4/12 and 3/12 so 4+3=7 so 7/12.
Next you divide by 3. To do this, find a larger denominator with a number that can be divided by 3.
7/12 to 14/24 and 21/36. 21 can be divided by 3.
Divide 21/36 by 3 and get 7/36. This can not be simplified any further.
Therefore your answer is D. 7/36.
