Final answer:
To find the number of bags Tomas obtains, we need to divide the total weight of mandarins by the weight of each bag.
Step-by-step explanation:
To find the number of bags Tomas obtains, we need to divide the total weight of mandarins by the weight of each bag. We are given that Tomas has 9 kg of mandarins, and each bag weighs three-quarters of a kilogram.
In order to perform the division, we convert 9 kg to grams by multiplying it by 1000. Then we divide the total weight of mandarins (9000 grams) by the weight of each bag (750 grams).
This gives us a total of 12 bags of mandarins.
