Step-by-Step Solutions:

#### First Row:
1. 77 × 25
- Break down 25 as \( 20 + 5 \):
\[
77 \times 25 = 77 \times (20 + 5) = (77 \times 20) + (77 \times 5)
\]
- Calculate each part:
\[
77 \times 20 = 1540
\]
\[
77 \times 5 = 385
\]
- Add the results:
\[
1540 + 385 = 1925
\]
- Answer: \( 1925 \)

2. 27 × 15
- Break down 15 as \( 10 + 5 \):
\[
27 \times 15 = 27 \times (10 + 5) = (27 \times 10) + (27 \times 5)
\]
- Calculate each part:
\[
27 \times 10 = 270
\]
\[
27 \times 5 = 135
\]
- Add the results:
\[
270 + 135 = 405
\]
- Answer: \( 405 \)

#### Second Row:
3. 24 × 49
- Break down 49 as \( 50 - 1 \):
\[
24 \times 49 = 24 \times (50 - 1) = (24 \times 50) - (24 \times 1)
\]
- Calculate each part:
\[
24 \times 50 = 1200
\]
\[
24 \times 1 = 24
\]
- Subtract the results:
\[
1200 - 24 = 1176
\]
- Answer: \( 1176 \)

4. 21 × 79
- Break down 79 as \( 80 - 1 \):
\[
21 \times 79 = 21 \times (80 - 1) = (21 \times 80) - (21 \times 1)
\]
- Calculate each part:
\[
21 \times 80 = 1680
\]
\[
21 \times 1 = 21
\]
- Subtract the results:
\[
1680 - 21 = 1659
\]
- Answer: \( 1659 \)

5. 38 × 52
- Use the distributive property:
\[
38 \times 52 = 38 \times (50 + 2) = (38 \times 50) + (38 \times 2)
\]
- Calculate each part:
\[
38 \times 50 = 1900
\]
\[
38 \times 2 = 76
\]
- Add the results:
\[
1900 + 76 = 1976
\]
- Answer: \( 1976 \)

6. 20 × 11
- Use the distributive property:
\[
20 \times 11 = 20 \times (10 + 1) = (20 \times 10) + (20 \times 1)
\]
- Calculate each part:
\[
20 \times 10 = 200
\]
\[
20 \times 1 = 20
\]
- Add the results:
\[
200 + 20 = 220
\]
- Answer: \( 220 \)

#### Third Row:
7. 30 × 15
- Use the distributive property:
\[
30 \times 15 = 30 \times (10 + 5) = (30 \times 10) + (30 \times 5)
\]
- Calculate each part:
\[
30 \times 10 = 300
\]
\[
30 \times 5 = 150
\]
- Add the results:
\[
300 + 150 = 450
\]
- Answer: \( 450 \)

8. 63 × 10
- Multiply by 10:
\[
63 \times 10 = 630
\]
- Answer: \( 630 \)

9. 39 × 36
- Use the distributive property:
\[
39 \times 36 = 39 \times (30 + 6) = (39 \times 30) + (39 \times 6)
\]
- Calculate each part:
\[
39 \times 30 = 1170
\]
\[
39 \times 6 = 234
\]
- Add the results:
\[
1170 + 234 = 1404
\]
- Answer: \( 1404 \)

10. 36 × 48
- Use the distributive property:
\[
36 \times 48 = 36 \times (50 - 2) = (36 \times 50) - (36 \times 2)
\]
- Calculate each part:
\[
36 \times 50 = 1800
\]
\[
36 \times 2 = 72
\]
- Subtract the results:
