Final answer:
Barry's dog weighs 11 7/8 pounds.
Step-by-step explanation:
To find the weight of Barry's dog, we need to multiply the weight of his cat by 2 3/8. First, we need to convert the mixed number 2 3/8 into an improper fraction. This is done by multiplying the whole number (2) by the denominator (8) and adding the numerator (3). This gives us 19/8. Now we can multiply 5 (the weight of the cat) by 19/8 to find the weight of the dog. To multiply fractions, multiply the numerators (5 times 19) to get 95, and multiply the denominators (8 times 1) to get 8. So, the dog weighs 95/8 pounds, which can be simplified to 11 7/8 pounds.
