Problem Statement: Mental Calculation (according to the model).
Solution Guide: Observe the sample example to mentally calculate the division of round thousands.
Answer:
- 8 thousand : 2 = 4 thousand
8,000 : 2 = 4,000
- 40 thousand : 5 = 8 thousand
40,000 : 5 = 8,000
- 36 thousand : 9 = 4 thousand
36,000 : 9 = 4,000
- 42 thousand : 7 = 6 thousand
42,000 : 7 = 6,000

5. Solve Exercise 5 Page 74 Math Grade 3 Textbook
Problem Statement: A fish sauce factory has produced 1,230 liters of fish sauce, and they want to pack it into equal-sized cans. Calculate and state the number of cans of fish sauce that can be packed in the following cases:
Solution Guide: Number of cans of fish sauce = Amount of fish sauce produced : amount of fish sauce per can.
Answer:
If 1,230 liters of fish sauce are packed into cans, each containing 2 liters, then we can pack 615 cans.
If 1,230 liters of fish sauce are packed into cans, each containing 3 liters, then we can pack 410 cans.
If 1,230 liters of fish sauce are packed into cans, each containing 5 liters, then we can pack 246 cans.
6. Solve Exercise 6 Page 74 Math Grade 3 Textbook
Problem Statement: Read the price of each item below and then answer the questions.
a) Buying a pack of yogurt with 6 bottles costs 25,800 dong. How much does each bottle of yogurt cost?
b) Buying a box of cream puffs with 8 pieces costs 42,400 dong. How much does each cream puff cost?
Solution Guide:
+ Observe the pictures, determine the prices of the items.
+ Price per bottle of yogurt = price of 1 pack of yogurt : 6.
+ Price per cream puff = price of 1 box of cream puffs : 8.
Answer:
a) Each bottle of yogurt costs:
25,800 : 6 = 4,300 (dong)
b) Each cream puff costs:
42,400 : 8 = 5,300 (dong)
Answers: a) 4,300 dong.
b) 5,300 dong.
