Rabbit A and C lost more than 1 oz, Rabbit B gained more than 1 oz, and Rabbit D lost less than 1 oz in total over the 3 weeks.
To find the total change in weight for each rabbit after 3 weeks, we need to sum the changes in weight for each week. Let's calculate this for each rabbit:
Rabbit A:
Week 1: -1 5/8
Week 2: -3/4
Week 3: 1 1/4
Total change = (-1 5/8) + (-3/4) + (1 1/4) = -1 5/8 - 3/4 + 5/4 = -2 7/8 ounces
Rabbit B:
Week 1: 1 3/16
Week 2: 1 1/4
Week 3: -1/8
Total change = (1 3/16) + (1 1/4) + (-1/8) = 1 3/16 + 1 1/4 - 1/8 = 2 5/8 ounces
Rabbit C:
Week 1: 2 3/8
Week 2: -1 1/4
Week 3: -7/8
Total change = (2 3/8) + (-1 1/4) + (-7/8) = 2 3/8 - 1 1/4 - 7/8 = -1 3/8 ounces
Rabbit D:
Week 1: -3/4
Week 2: 1/8
Week 3: -7/16
Total change = (-3/4) + (1/8) + (-7/16) = -3/4 + 1/8 - 7/16 = -15/16 ounces
Now, we can categorize the total changes for each rabbit:
Rabbit A: Less than or equal to -1 oz
Rabbit B: Greater than or equal to 1 oz
Rabbit C: Less than or equal to -1 oz
Rabbit D: Less than or equal to -1 oz
In summary, Rabbit A and Rabbit C experienced a total weight loss of less than or equal to -1 oz, Rabbit B had a total weight gain greater than or equal to 1 oz, and Rabbit D had a total weight loss of less than or equal to -1 oz.
