2. Solve Exercise 2 on Page 23 of Math Grade 4 Textbook
Problem Statement:
Fill in the appropriate numbers in the blanks:
a) 1 swallow = 10 kg 5 swallows = 50 kg 1 swallow 7 kg = 17 kg
10kg = 1 swallow 8 swallows = 80 kg 5 swallows 3kg = 53 kg
b) 1 ton = 10 swallows 4 tons = 40 swallows
10 swallows = 1 ton 2 tons = 200 kg
1 ton = 100 kg 9 tons = 900 kg
100 kg = 1 ton 4 tons 60 kg = 460 kg
c) 1 ton = 10 tons 3 tons = 30 tons
10 tons = 1 ton 8 tons = 80 tons
1 ton = 1 000kg 5 tons = 5 000 kg
Solution Method:
* Apply the unit conversion table for weight:
- Larger than kilogram includes units: Ton; tạ; swallow
- Intermediate unit: Kilogram
- Smaller than kilogram includes units: Hectogram (hg); Decagram (dag); gram (g).
* Each weight unit is 10 times the next smaller unit.
Answers:
Check the conversion between units to solve this exercise!

3. Solution for Problem 3 on Page 23 of Math Grade 4 Textbook
Problem Statement:
Calculate
18 swallows + 26 swallows 648 tons - 75 tons
135 tons x 4 512 tons : 8
Solution Method:
- Observation: All numbers in the expressions are in the same unit of weight.
- Approach: Perform calculations as usual, but remember to include the unit of weight with the results.
Answers:
18 swallows + 26 swallows = 44 swallows
648 tons - 75 tons = 573 tons
135 tons x 4 = 540 tons
512 tons : 8 = 64 tons
4. Solving Problem 4 from Page 23 of Math Grade 4 Textbook
Problem Statement:
A car transported 3 tons of salt in the first trip, and in the subsequent trip, it carried 3 tạ more than the first trip. How many tạ of salt did both trips carry together?
Solution Method:
1. Observation
- The problem states:
+ In the first trip, the car carried 3 tons of salt
+ In the subsequent trip, the car carried more than the first trip by 3 tạ
- The problem requires: Finding the total number of tạ of salt carried by both trips.
2. Solution Approach
- Step 1: Convert tons to tạ
- Step 2: Find the number of tạ of salt carried by the car in the subsequent trip
- Step 3: Find the total number of tạ of salt carried by both trips.
Answers:
Convert: 3 tons = 30 tạ
The amount of salt the car carried in the subsequent trip is: 30 + 3 = 33 (tạ).
After both trips, the amount of salt the car carried is: 30 + 33 = 63 (tạ).
So, the total amount of salt carried is: 63 (tạ).
