Final answer:
To calculate the number of full bags of Arabica coffee beans, divide the weight of the beans (9/10 lb) by the weight of one bag (1/16 lb), which equals 14.4 and rounds down to 14 full bags.
Step-by-step explanation:
To find out how many full bags of Arabica coffee beans there are, we need to divide the total weight of Arabica beans by the weight of one bag. The grocery store sells the Arabica coffee beans by the pound, and the weight is given as 9/10 of a pound. Each bag holds 1/16 of a pound of coffee beans.
To determine the number of bags, we perform the following division: 9/10 lb ÷ 1/16 lb/bag. This calculation is equivalent to 9/10 × 16/1, which simplifies to 144/10 and then to 14.4. Since you can only have a full bag, you need to round down to the nearest whole number, which is 14 full bags of Arabica coffee beans.
