Question

a football field is 9600 square yards. if 1200 pounds of fertilizer are spread evenly across the entire field, how many pounds of fertilizer were spread over an area of the field totaling 3600 square yards?

Answer 1

9600 yd² = 12000 pounds of fertiliser

Find 1 yd²

1 yd² = 12000 ÷ 9600

1 yd² = 1.25 pounds

Find 3600 yd²:

1 yd² = 1.25 pounds

3600 yd² = 1.25 x 3600 = 4500 pounds

Answer: There is a total of 4500 pounds of fertiliser spread in an area of 3600 yd²

Answer 2

1200 pounds of fertilizer required for 9600 sq. yards.

=> 1 sq. yard requires 1200/9600 = 1/8 pounds of fertilizer

3600 sq. yards would require : 3600 * 1/8 = 3600/8 = 450 pounds -
