问题 You are applying fertilizer to your backyard. The rectangular yard measures 40 feet wide and 70 feet long. You use 6 pounds of fertilizer to treat 700 square feet. The fertilizer comes in 8-pound bags. How many bags of fertilizer will you need to complete the job?

解析 The question asks you to determine the number of bags of fertilizer that will cover your rectangular backyard. According to information in the problem, 6 pounds of fertilizer can cover 700 square feet. Calculate the area of the backyard. The area of a rectangle is determined by multiplying the length(70 feet)by the width(40 feet):
70 × 40 = 2,800
The area of the backyard is 2,800 square feet. The problem states that 6 pounds of fertilizer can cover 700 square feet. Calculate the number of times that 700 will go into 2,800:
2,800 ÷ 700 = 4
You will need 4 times 6 pounds of fertilizer to treat 2,800 square feet:
4 × 6 = 24
Since you will need a total of 24 pounds of fertilizer to treat the backyard, and each bag of fertilizer weighs 8 pounds, divide 24 by 8 to find the number of bags of fertilizer you will need:
24 ÷ 8 = 3
You will need 3 bags of fertilizer to treat a backyard that measures 2,800 square feet.
