Answer 1

ADD them

Step-by-step explanation:

11 1/5+ 5 1/4 is 19/20

If you were subtracting the fractions your answer would be different (look at attachment)

Answer 2

Answer:

To find the difference of the weights, you must subtract the smaller number from the bigger number.

First, we want to convert both mixed numbers to improper fractions

5 1/4 = 20/4 + 1/4 = 21/4

11 1/5 = 55/5 + 1/5 = 56/5

Now, we make the denominator for both to be equal to 20, and subtract to get the answer: 119/20, or about 5.95 pounds.

Let me know if this helps!
