For example the problem above is the same as: 2 ¤4 + 2 ¤4 + 2 ¤4 If we shade in 2 /4 on the fractions below 3 times we can see a visual representation of the problem. 2 ¤4 × 3 = 2 ¤4 × 3 = 1 2 /4 After shading it in we can see why 2 /4 three times is equal to 1 whole and 2 /4. 1-10 92 83 75 67 58 50 42 33 25 17 11-12 8 0 1) 4 ¤8 × 4 = 2) 5 ¤6 × 6 = 3) 3 ¤4 × 6 = 4) 3 ¤6 × 6 = 5) 4 ¤12 × 4 = 6) 2 ¤3 × 4 = 7) 7 ¤12 × 4 = 8) 3 ¤8 × 6 = 9) 1 ¤4 × 4 = 10) 8 ¤10 × 4 = 11) 6 ¤8 × 3 = 12) 2 ¤3 × 2 = 1. 2 2. 5 3. 4 2 ¤4 4. 3 5. 1 4 ¤12 6. 2 2 ¤3 7. 2 4 ¤12 8. 2 2 ¤8 9. 1 10. 3 2 ¤10 11. 2 2 ¤8 12. 1 1 ¤3 Multiplying Fractions by Whole Numbers (visual) Use the visual model to solve each problem. 1

    • Math www.CommonCoreSheets.com Name: Answers When multiplying a fraction and a whole number you can estimate the answer by remember that the fraction is just part of a number. 5 × 6 2 /3 = In the example above, 6 2 /3 is larger than 6 but less than 7. So we know the answer is going to be between 5 × 6 and 5 × 7. 5 × 6 2 /3 = 33 1 /3 The actual answer is 33 1 /3 which is between 5 × 6 (30) and 5 × 7 (35). 1-10 92 83 75 67 58 50 42 33 25 17 11-12 8 0 1) 7 1 ¤4 × 7 = A. 42 3 ¤4 B. 48 3 ¤4 C. 50 3 ¤4 D. 47 1 ¤4 2) 5 8 ¤10 × 7 = A. 43 6 ¤10 B. 40 6 ¤10 C. 44 6 ¤10 D. 28 6 ¤10 3) 5 1 ¤7 × 4 = A. 28 4 ¤7 B. 18 4 ¤7 C. 26 4 ¤7 D. 20 4 ¤7 4) 8 4 ¤7 × 7 = A. 60 B. 54 C. 64 D. 65 5) 4 × 7 2 ¤3 = A. 30 2 ¤3 B. 35 2 ¤3 C. 24 2 ¤3 D. 36 2 ¤3 6) 3 × 8 2 ¤8 = A. 24 6 ¤8 B. 21 2 ¤8 C. 30 6 ¤8 D. 28 6 ¤8 7) 6 × 2 8 ¤10 = A. 20 8 ¤10 B. 19 8 ¤10 C. 21 8 ¤10 D. 16 8 ¤10 8) 6 × 6 8 ¤9 = A. 41 3 ¤9 B. 34 3 ¤9 C. 43 3 ¤9 D. 35 3 ¤9 9) 9 × 8 4 ¤9 = A. 83 4 ¤9 B. 76 C. 82 D. 70 4 ¤9 10) 5 1 ¤7 × 8 = A. 41 1 ¤7 B. 56 1 ¤7 C. 50 1 ¤7 D. 38 1 ¤7 11) 6 × 6 5 ¤10 = A. 39 B. 34 5 ¤10 C. 43 D. 44 5 ¤10 12) 4 8 ¤9 × 3 = A. 14 6 ¤9 B. 16 6 ¤9 C. 10 8 ¤9 D. 18 6 ¤9 1.

So we know the answer is going to be between 5 × 6 and 5 × 7. 5 × 6 2 /3 = 33 1 /3 The actual answer is 33 1 /3 which is between 5 × 6 (30) and 5 × 7 (35).
