Guidelines for solving exercises on page 24 Math 4 including solution methods
1. Solve exercise 1 page 24 Math 4 textbook
Problem:
Fill in the blanks with appropriate numbers:
a) 1dag = 10g 1 hg = 10 dag
10g = 1 dag 10 dag = 1 hg
b) 4 dag = 40 g 3 kg = 30 hg 2 kg 300 g = (2 000 + 300) = 2 300 g
8 hg = 80 dag 7 kg = 7 000 g 2 kg 30 g = (2 000 + 30) = 2 030 g
Solution method:
Review the detailed instructions in solving exercise 2 page 23 Math 4 textbook.
Answer:
Kids, review the weight conversion chart and fill in the blanks:
a) 1 dag = 10 g 1 hg = 10 dag
10g = 1 dag 10 dag = 1 hg
b) 4 dag = 40 g 3 kg = 30 hg 2 kg 300 g = (2 000 + 300) = 2 300 g
8 hg = 80 dag 7 kg = 7 000 g 2 kg 30 g = (2 000 + 30) = 2 030 g
2. Solve exercise 2 page 24 Math 4 textbook
Problem:
Calculate
380 g + 195 g 452 hg x 3
928 dag - 274 dag 768 hg : 6
Solution method:
* Observation: All numbers in the expressions share the same weight unit.
* Approach: Perform addition, subtraction, multiplication, and division as usual; pay attention to include the corresponding weight units in the results.
Answers:
+) 380 g + 195 g +) 928 dag - 274 dag
We have: 380 + 195 = 575 We have: 928 - 274 = 654
So 380 g + 195 g = 575 g So 928 dag - 274 dag = 654 dag
+) 452 hg x 3 +) 768 hg : 6
We have: 452 x 3 = 1 356 We have: 768 : 6 = 128
So 452 hg x 3 = 1 356 hg So 768 hg : 6 = 128 hg
3. Solve exercise 3 page 24 SGK toán 4
Solution method:
- Convert to the same unit of weight (change to the smallest unit of weight according to the given problem)
- Compare as comparing two normal numbers.
4. Solve exercise 4 page 24 SGK toán 4
Exercise:
There are 4 packages of cakes, each package weighs 150 grams, and 2 packages of candies, each package weighs 200 grams. How many kilograms of cakes and candies are there in total?
Solution Method:
* Observation:
- Given problem:
+ There are 4 packages of cakes, each weighs 150 grams
+ There are 2 packages of candies, each weighs 200 grams
- Problem requires finding: Total weight of four packages of cakes and two packages of candies in kilograms.
* Solution:
- Step 1: Find the total weight of four packages of cakes by multiplying the weight of one package by 4.
- Step 2: Find the total weight of two packages of candies by multiplying the weight of one package by 2.
- Step 3: Find the total weight of four packages of cakes and two packages of candies by adding the two results obtained above together.
- Step 4: Convert the weight from grams to kilograms
- Step 5: Conclusion.
Answer:
The total weight of 4 packages of cakes is:
150 g x 4 = 600 g.
The total weight of 2 packages of candies is:
200 g x 2 = 400 g.
The total weight of four packages of cakes and two packages of candies is:
600 g + 400 g = 1,000 g = 1 kg.
Answer: 1 kg
