Question 6.

600 ÷ 2 = ____

Answer:

The division of the given number is 300.

Explanation:

Use a multiplication pattern.

3 × 2 = 6 → 6 ÷ 2 = 3

3 × 20 = 60 → 60 ÷ 2 = 30

3 × 200 = 600 → 600 ÷ 2 = 300

The division of the given number is 300.

Use a basic fact and place value.

6 ÷ 2 = 3 ← basic fact

60 ÷ 2 = 30 ← 30 = 30 × 2. So, 60 = 20 × 3.

600 ÷ 2 = 300 ← 300 = 200 × 3. So 600 ÷ 2 = 300.

Question 7.

7,200 ÷ 9 = ____

Answer:

The division of the given number is 800.

Explanation:

Use a multiplication pattern.

9 × 8 = 72 → 72 ÷ 9 = 8

9 × 80 = 720 → 720 ÷ 9 = 80

9 × 800 = 7,200 → 7,200 ÷ 9 = 800

The division of the given number is 800.

Use a basic fact and place value.

72 ÷ 9 = 8 ← basic fact

720 ÷ 9 = 80 ← 720 = 80 × 9. So, 720 = 80 × 9.

7,200 ÷ 9 = 800 ← 7,200 = 800 × 9. So 7,200 ÷ 9 = 800.

Question 8.

6,400 ÷ 8 = ____

Answer:

The division of the given number is 800.

Explanation:

Use a multiplication pattern.

8 × 8 = 64 → 64 ÷ 8 = 8

8 × 80 = 640 → 640 ÷ 8 = 80

8 × 6,400 = 6,400 → 6,400 ÷ 8 = 800

The division of the given number is 800.

Use a basic fact and place value.

64 ÷ 8 = 8 ← basic fact

640 ÷ 8 = 80 ← 80 = 80 × 8. So, 640 = 80 × 8.

6,400 ÷ 8 = 800 ← 800 = 800 × 8. So 6,400 ÷ 8 = 800.

**Estimate.**

Question 9.

715 ÷ 8

Answer:

The estimated value is 90.

Explanation:

Here, we will round off 715 to 720. So the division of 720÷ 8 is 90. So the estimated value is 90.

Question 10.

2,660 ÷ 9

Answer:

The estimated value is 300.

Explanation:

Here, we will round off 2,660 to 2,700. So the division of 2,700÷ 9 is 300. So the estimated value is 300.

Question 11.

8,099 ÷ 9

Answer:

The estimated value is 900.

Explanation:

Here, we will round off 8,099 to 9,000. So the division of 9,000÷ 9 is 900. So the estimated value is 900.

**Use the Distributive Property or partial quotients to divide.**
