Answer:

Practice

1. Solve Exercise 1 Page 15 Math Grade 3 Textbook

Problem: Number?

Guidance for solving: Addend + Addend = Sum.

Answer:

2. Solve Exercise 2 Page 15 Math Grade 3 Textbook

Problem: Mental calculation.

Guidance for solving: The expression involves only addition and subtraction; perform the operations from left to right.

Answer:
5,000 + 2,000 + 1,000 = 7,000 + 1,000
= 8,000
1,800 + 1,200 + 6,000 = 3,000 + 6,000
= 9,000
4,000 + 3,000 + 3,000 = 7,000 + 3,000
= 10,000
4,900 + 500 + 100 = 5,400 + 100
= 5,500

4. Solving Problem 4 Page 15 Math Book Grade 3

Problem: Uncle Tam's family harvested rambutans and mangoes. Rambutans weigh 2,320 kg. The weight of mangoes is 520 kg more than rambutans. How much total weight of rambutans and mangoes did Uncle Tam's family harvest?

Solution:
Step 1: Calculate the weight of mangoes = weight of rambutans + 520 kg.
Step 2: Calculate the total weight of rambutans and mangoes harvested = Weight of mangoes + weight of rambutans.

Answer:
The weight of mangoes Uncle Tam's family harvested is:
2,320 + 520 = 2,840 (kg)
Uncle Tam's family harvested a total weight of rambutans and mangoes:
2,320 + 2,840 = 5,160 (kg)
Answer: 5,160 kg

5. Solving Problem 5 Page 15 Math Book Grade 3

Problem: What number?

The distance from Ho Chi Minh City to Sa Pa town, passing through the capital Hanoi, is .?. km.

Solution: The distance from Ho Chi Minh City to Sa Pa town passing through the capital Hanoi = Distance from Ho Chi Minh City to Hanoi + Distance from Hanoi to Sa Pa town.

Answer:
The distance from Ho Chi Minh City to Sa Pa town, passing through the capital Hanoi is:
1,726 + 320 = 2,046 (km).
So, we fill in the number 2046.
