Multiplication Problems:
1.
a) \( 2564 \times 3 \)
- Multiply each digit of 2564 by 3:
\[
2564 \times 3 = (2000 \times 3) + (500 \times 3) + (60 \times 3) + (4 \times 3)
\]
\[
= 6000 + 1500 + 180 + 12 = 7692
\]
-
Answer: \( 7692 \)
2.
b) \( 986 \times 6 \)
- Multiply each digit of 986 by 6:
\[
986 \times 6 = (900 \times 6) + (80 \times 6) + (6 \times 6)
\]
\[
= 5400 + 480 + 36 = 5916
\]
-
Answer: \( 5916 \)
3.
c) \( 1529 \times 3 \)
- Multiply each digit of 1529 by 3:
\[
1529 \times 3 = (1000 \times 3) + (500 \times 3) + (20 \times 3) + (9 \times 3)
\]
\[
= 3000 + 1500 + 60 + 27 = 4587
\]
-
Answer: \( 4587 \)
4.
d) \( 498 \times 9 \)
- Multiply each digit of 498 by 9:
\[
498 \times 9 = (400 \times 9) + (90 \times 9) + (8 \times 9)
\]
\[
= 3600 + 810 + 72 = 4482
\]
-
Answer: \( 4482 \)
5.
e) \( 657 \times 3 \)
- Multiply each digit of 657 by 3:
\[
657 \times 3 = (600 \times 3) + (50 \times 3) + (7 \times 3)
\]
\[
= 1800 + 150 + 21 = 1971
\]
-
Answer: \( 1971 \)
6.
f) \( 1245 \times 5 \)
- Multiply each digit of 1245 by 5:
\[
1245 \times 5 = (1000 \times 5) + (200 \times 5) + (40 \times 5) + (5 \times 5)
\]
\[
= 5000 + 1000 + 200 + 25 = 6225
\]
-
Answer: \( 6225 \)
