\]
So, the answer is:
\[
\boxed{600}
\]

3 a. \(100 \times \_\_\_\_ = 600\)

To find the missing number, divide 600 by 100:
\[
600 \div 100 = 6
\]
So, the answer is:
\[
\boxed{6}
\]

3 b. \(50 \times \_\_\_\_ = 300\)

To find the missing number, divide 300 by 50:
\[
300 \div 50 = 6
\]
So, the answer is:
\[
\boxed{6}
\]

4 a. \(8 \times \_\_\_\_ = 5600\)

To find the missing number, divide 5600 by 8:
\[
5600 \div 8 = 700
\]
So, the answer is:
\[
\boxed{700}
\]

4 b. \(\_\_\_\_ \times 9 = 4500\)

To find the missing number, divide 4500 by 9:
\[
4500 \div 9 = 500
\]
So, the answer is:
\[
\boxed{500}
\]

5 a. \(\_\_\_\_ \times 4 = 280\)

To find the missing number, divide 280 by 4:
\[
280 \div 4 = 70
\]
So, the answer is:
\[
\boxed{70}
\]

5 b. \(90 \times \_\_\_\_ = 180\)

To find the missing number, divide 180 by 90:
\[
180 \div 90 = 2
\]
So, the answer is:
\[
\boxed{2}
\]

6 a. \(\_\_\_\_ \times 4 = 400\)

To find the missing number, divide 400 by 4:
\[
400 \div 4 = 100
\]
So, the answer is:
\[
\boxed{100}
\]

6 b. \(\_\_\_\_ \times 8 = 4000\)

To find the missing number, divide 4000 by 8:
\[
4000 \div 8 = 500
\]
So, the answer is:
\[
\boxed{500}
\]

7 a. \(\_\_\_\_ \times 9 = 3600\)

To find the missing number, divide 3600 by 9:
\[
3600 \div 9 = 400
\]
So, the answer is:
\[
\boxed{400}
\]

7 b. \(\_\_\_\_ \times 70 = 140\)

To find the missing number, divide 140 by 70:
\[
140 \div 70 = 2
\]
So, the answer is:
\[
\boxed{2}
\]

8 a. \(\_\_\_\_ \times 600 = 5400\)

To find the missing number, divide 5400 by 600:
\[
5400 \div 600 = 9
\]
So, the answer is:
\[
\boxed{9}
\]

8 b. \(100 \times \_\_\_\_ = 400\)

To find the missing number, divide 400 by 100:
\[
400 \div 100 = 4
\]
So, the answer is:
\[
\boxed{4}
\]

9 a. \(4 \times \_\_\_\_ = 3200\)

To find the missing number, divide 3200 by 4:
\[
3200 \div 4 = 800
\]
So, the answer is:
\[
\boxed{800}
\]

9 b. \(500 \times \_\_\_\_ = 2500\)

To find the missing number, divide 2500 by 500:
\[
2500 \div 500 = 5
\]
So, the answer is:
\[
\boxed{5}
\]

10 a. \(7 \times \_\_\_\_ = 490\)

To find the missing number, divide 490 by 7:
\[
490 \div 7 = 70
\]
So, the answer is:
\[
\boxed{70}
\]

10 b. \(30 \times \_\_\_\_ = 180\)

To find the missing number, divide 180 by 30:
\[
180 \div 30 = 6
\]
So, the answer is:
\[
\boxed{6}
\]
