Hello!

ANSWER:

36 students have a dog as a pet, and 30 students have a cat as a pet.

EXPLANATION:

Let's quickly convert these fractions to decimals by dividing their numerators by their denominators.

4 ÷ 5 = 0.8

2 ÷ 3 = 0.6666666667

Now, multiply the decimal forms by the number of students in Mrs. Hu's class.

0.8 × 45 = 36

0.(6)7 × 45 = 30
