2. 2. For example 3.97 x 6
3. 3. For example 3.97 x 6 Set the question out like this:
4. 4. For example 3.97 x 6 Set the question out like this: T U . t h 3 . 9 7 X 6 2 9 .8 2
5. 5. Always make sure that the decimal points are lined up correctly T U . t h 3 . 9 7 X 6 2 9 .8 2
6. 6. Always make sure that the decimal points are lined up correctly T U . t h 3 . 9 7 X 6 2 9 .8 2
7. 7. Then multiply the number in the hundredths column (7) T U . t h 3 . 9 7 X 6 2 9 .8 2
8. 8. Then multiply the number in the hundredths column (7) by 6 T U . t h 3 . 9 7 X 6 2 9 .8 2
9. 9. 7x6= T U . t h 3 . 9 7 X 6 2 9 .8 2
10. 10. 7 x 6 = 42 T U . t h 3 . 9 7 X 6 2 9 .8 2
11. 11. 7 x 6 = 42 The 2 is placed in the answer bar, in the hundredths column T U . t h 3 . 9 7 X 6 2 9 .8 2
12. 12. 7 x 6 = 42 The 2 is placed in the answer bar, in the hundredths column T U . t h 3 . 9 7 X 6 2 9 .8 2
13. 13. 7 x 6 = 42 The 4 is placed under the answer bar, under the tenths column T U . t h 3 . 9 7 X 6 2 9 .8 2
14. 14. 7 x 6 = 42 The 4 is placed under the answer bar, under the tenths column T U . t h 3 . 9 7 X 6 2 9 .8 4 2
15. 15. Next, multiply the number in the tenths column (9) T U . t h 3 . 9 7 X 6 2 9 .8 4 2
16. 16. Next, multiply the number in the tenths column (9) by 6 T U . t h 3 . 9 7 X 6 2 9 . 8 2 4
17. 17. 9x6= T U . t h 3 . 9 7 X 6 2 9 . 8 2 4
18. 18. 9 x 6 = 54 T U . t h 3 . 9 7 X 6 2 9 . 8 2 4
19. 19. 9 x 6 = 54 This is added to the 4 from under the tenths column T U . t h 3 . 9 7 X 6 2 9 . 8 2 4
20. 20. 54 + 4 = 58 T U . t h 3 . 9 7 X 6 2 9 . 8 2 4
21. 21. 54 + 4 = 58 The 8 is put in the tenths column T U . t h 3 . 9 7 X 6 2 9 . 8 2 4
22. 22. 54 + 4 = 58 The 5 is placed under the answer bar, under the units column T U . t h 3 . 9 7 X 6 2 9 . 8 2 5 4
23. 23. Now, multiply the number in the units column (3) T U . t h 3 . 9 7 X 6 2 9 . 8 2 5 4
24. 24. Now, multiply the number in the units column (3) by 6 T U . t h 3 . 9 7 X 6 2 9 . 8 2 5 4
25. 25. 3 x 6 = 18 T U . t h 3 . 9 7 X 6 2 9 . 8 2 5 4
26. 26. 3 x 6 = 18 This is added to the 5 from under the units column T U . t h 3 . 9 7 X 6 2 9 . 8 2 5 4
27. 27. 18 + 5 = 23 T U . t h 3 . 9 7 X 6 2 3 . 8 2 5 4
28. 28. 18 + 5 = 23 The 3 is placed in the units column T U . t h 3 . 9 7 X 6 2 9 . 8 2 5 4
29. 29. 18 + 5 = 23 The 3 is placed in the units column T U . t h 3 . 9 7 X 6 2 3 . 8 2 5 4
30. 30. 18 + 5 = 23 The 2 is placed in the tens column T U . t h 3 . 9 7 X 6 2 3 . 8 2 5 4
31. 31. 18 + 5 = 23 The 2 is placed in the tens column T U . t h 3 . 9 7 X 6 2 3 . 8 2 5 4
32. 32. 3.97 x 6 = 23.82 T U . t h 3 . 9 7 X 6 2 3 . 8 2 5 4
