Corey wants to buy grass seed for his yard, which measures 252 square feet. Each bag of grass seed covers 12 square feet. What fraction of his yard will one bag of seed cover?

fraction=12/252

21 To determine the fraction of Corey's yard that one bag of grass seed will cover, we first need to find out how many bags of grass seed he will need to cover the entire yard.

To do that, we divide the total area of Corey's yard (252 square feet) by the area covered by one bag of grass seed (12 square feet):

252 square feet ÷ 12 square feet = 21 bags of grass seed

So, Corey will need a total of 21 bags of grass seed to cover his entire yard.

Next, to find the fraction of his yard one bag of seed will cover, we divide the area covered by one bag of seed (12 square feet) by the total area of Corey's yard (252 square feet):

12 square feet ÷ 252 square feet = 1/21

Therefore, one bag of grass seed will cover 1/21 fraction of Corey's yard.
