Answer:
14 3/4 pounds
Step-by-step explanation:
This is an addition problem
All your variables/foods are in pounds, so there is no need to convert them to different units
By 1/1/2, I'm going to assume that's 1 and 1/2. Same with the other.
Then just add!
12 + 1 1/2 + 1 1/4 = 14 3/4
If you are confused on how to add halves to fourths, what you have to do is find a common denominator (bottom of the fraction)
Since 2 x 2 = 4, multiply 1/2 by 2 on both top and bottom
This is essentially multiplying by 1, but it will give the equivalent fraction with a different denominator.
2/4 + 1/4 = 3/4
Therefore, your answer is 14 3/4 pounds
