Final answer:
Mike's cat weighs 42 ounces more than his bird. This is determined by converting the cat's weight to ounces (48 ounces + 9 ounces) and then subtracting the weight of the bird (15 ounces).
Step-by-step explanation:
To determine how much more Mike’s cat weighs than his bird, we need to convert the cat's weight to ounces and then subtract the bird's weight from that total.
- First, convert Mike's cat's weight from pounds to ounces. Since there are 16 ounces in a pound, multiply 3 pounds by 16 to get the total number of ounces. 3 × 16 = 48 ounces.
- Add the additional 9 ounces to the total. 48 ounces + 9 ounces = 57 ounces.
- Now subtract the bird's weight from the cat's weight in ounces. 57 ounces - 15 ounces = 42 ounces.
Therefore, Mike's cat weighs 42 ounces more than his bird.
