Problem Statement:
a) Choose two expressions with the same value:
b) Calculate the value of each expression below:
32 x (15 - 6)
244 - 124 ÷ 4
180 ÷ (3 x 2)
Solution Approach:
a) Observe and connect expressions with the same value.
b) - For expressions containing parentheses, perform operations inside the parentheses first.
- For expressions involving multiplication, division, addition, and subtraction, perform multiplication and division first, then perform addition and subtraction.
Answer:
a)
b)
32 x (15 - 6) = 32 x 9 = 288
244 - 124 ÷ 4 = 244 - 31 = 213
180 ÷ (3 x 2) = 180 ÷ 6 = 30

Problem Statement:
Hiền, Hải, and Đức bought various types of cakes at a pastry shop as follows:
- Hiền bought 4 boxes of cakes, each box containing 3 orange-flavored cakes, totaling 36,000 dong.
- Hải bought 5 boxes of cakes, each box containing 2 strawberry-flavored cakes, totaling 50,000 dong.
- Đức bought 3 boxes of cakes, each box containing 4 chocolate-flavored cakes, totaling 48,000 dong.
According to me, among the types of cakes above, which type of cake has the highest selling price, and which type of cake has the lowest selling price?
Solution Approach:
- Find the price of 1 cake of each flavor = Total money spent on that type of cake : number of cake boxes : number of cakes in each box
- Compare the price of 1 cake for different flavors and draw a conclusion.
Answer:
The price of 1 orange-flavored cake is:
36,000 : 4 : 3 = 3,000 (dong)
The price of 1 strawberry-flavored cake is:
The price of one chocolate-flavored cake is:
50,000 : 5 : 2 = 5,000 (dong)
The price of one chocolate-flavored cake is:
48,000 : 3 : 4 = 4,000 (dong)
