Explanation:
To find out how many pounds of grass seed each lawn got, we need to divide the total amount of grass seed spread by the number of lawns.
First, we need to convert the mixed number 7 1/2 to an improper fraction:
7 1/2 = (2 x 7 + 1)/2 = 15/2
So Green Grass Landscaping spread 15/2 pounds of grass seed.
To find out how many pounds of grass seed each lawn got, we divide the total amount by the number of lawns:
15/2 ÷ 10 = (15/2) ÷ (10/1) = (15/2) x (1/10) = 15/20 = 3/4
Therefore, each lawn received 3/4 of a pound of grass seed.
