1. The company replaces one-third of its fleet every year.

The fleet consists of 75 cars.

One-third of 75 is 75 / 3 = 25.

So, it replaces 25 cars every year.

2. In terms of full games, he gets (9 games) of playing time.

3. Jack grows vegetables on 4/3 acre. Sam grows vegetable on 5/4 acre. Which is bigger, 4/3 or 5/4?

4/3 is bigger.

So, Jack has the biggest area of vegetables.

The area of the garage = 528 square feet Let the area of the house be Y square feet The total area of the house and garage should be less that 3000 square feet. Therefore, Area of the house + Area of the garage <= 3000 square feet Y + 528 square feet <= 3000 Square feet Y <= 3000 Square feet - 528 Square feet Y <= 2472 Square feet Therefore, the area of the house should be less than 2472 Square feet.
