  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
