Solution:

1. Set up the long multiplication.

2. Calculate 7 x 8, which is 56.

Since 56 is two-digit, we carry the first digit 5 to the next column.

3. Calculate 6 x 8, which is 48. Now add the carry digit of 5, which is 53.

Since 53 is two-digit, we carry the first digit 5 to the next column.

4. Calculate 5 x 8, which is 40. Now add the carry digit of 5, which is 45.

Since 45 is two-digit, we carry the first digit 4 to the next column.

5. Calculate 4 x 8, which is 32. Now add the carry digit of 4, which is 36.

Since 36 is two-digit, we carry the first digit 3 to the next column.

6. Bring down the carry digit of 3.

7. Calculate 7 x 5, which is 35.

Since 35 is two-digit, we carry the first digit 3 to the next column.

8. Calculate 6 x 5, which is 30. Now add the carry digit of 3, which is 33.

Since 33 is two-digit, we carry the first digit 3 to the next column.

9. Calculate 5 x 5, which is 25. Now add the carry digit of 3, which is 28.

Since 28 is two-digit, we carry the first digit 2 to the next column.

10. Calculate 4 x 5, which is 20. Now add the carry digit of 2, which is 22.

Since 22 is two-digit, we carry the first digit 2 to the next column.

11. Bring down the carry digit of 2.

12. Calculate 7 x 2, which is 14.

Since 14 is two-digit, we carry the first digit 1 to the next column.

13. Calculate 6 x 2, which is 12. Now add the carry digit of 1, which is 13.

Since 13 is two-digit, we carry the first digit 1 to the next column.

14. Calculate 5 x 2, which is 10. Now add the carry digit of 1, which is 11.

Since 11 is two-digit, we carry the first digit 1 to the next column.

15. Calculate 4 x 2, which is 8. Now add the carry digit of 1, which is 9.

16. Calculate 7 x 3, which is 21.

Since 21 is two-digit, we carry the first digit 2 to the next column.

17. Calculate 6 x 3, which is 18. Now add the carry digit of 2, which is 20.

Since 20 is two-digit, we carry the first digit 2 to the next column.

18. Calculate 5 x 3, which is 15. Now add the carry digit of 2, which is 17.

Since 17 is two-digit, we carry the first digit 1 to the next column.

19. Calculate 4 x 3, which is 12. Now add the carry digit of 1, which is 13.

Since 13 is two-digit, we carry the first digit 1 to the next column.

20. Bring down the carry digit of 1.

21. Calculate 36536 + 228350 + 913400 + 13701000, which is 14879286

22. Place the decimal.

45.67 has 2 decimal places, and 32.58 has 2 decimal places.

Therefore, the answer should have 2 + 2 = 4 decimal places.

23. Therefore, 45.67 x 32.58 = 1487.9286.

1487.92861487.9286

Done!
