Final answer:
Gill can cover a total of 469.5 square feet with her 3 3/4 bags of soil by multiplying the amount of soil by the area one bag covers and then converting to an improper fraction before calculating.
Step-by-step explanation:
Gill has 3 3/4 bags of soil to put in her garden, and each bag will cover 125.3 ft². To find out the total area Gill can cover with the soil, we need to multiply the amount of soil she has by the area one bag can cover. First, let's convert 3 3/4 to an improper fraction which is 15/4 (3×4 + 3 = 15). Now, we multiply 15/4 by 125.3 ft² to get the total area covered:
(15/4) × 125.3 ft² = (15 × 125.3) / 4 ft²
(15 × 125.3) / 4 ft² = 469.5 ft²
Gill will be able to cover 469.5 square feet with 3 3/4 bags of soil.
