A farmer has 23 acres on his horse farm. He wants to have at least 1.8 acres for each horse for proper grazing. How can he determine if he has enough acreage for 12 horses?

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
