Multiplying in columns: Grade 5 Multiplication Worksheet 3 with 12 problems for practice.

Here are the solutions for the multiplication problems. I have calculated each one step-by-step to ensure accuracy.

1. $428 \times 77$
* $428 \times 7 = 2,996$
* $428 \times 70 = 29,960$
* $2,996 + 29,960 = 32,956$

2. $864 \times 56$
* $864 \times 6 = 5,184$
* $864 \times 50 = 43,200$
* $5,184 + 43,200 = 48,384$

3. $744 \times 94$
* $744 \times 4 = 2,976$
* $744 \times 90 = 66,960$
* $2,976 + 66,960 = 69,936$

4. $515 \times 73$
* $515 \times 3 = 1,545$
* $515 \times 70 = 36,050$
* $1,545 + 36,050 = 37,595$

5. $763 \times 39$
* $763 \times 9 = 6,867$
* $763 \times 30 = 22,890$
* $6,867 + 22,890 = 29,757$

6. $984 \times 46$
* $984 \times 6 = 5,904$
* $984 \times 40 = 39,360$
* $5,904 + 39,360 = 45,264$

7. $476 \times 88$
* $476 \times 8 = 3,808$
* $476 \times 80 = 38,080$
* $3,808 + 38,080 = 41,888$

8. $417 \times 62$
* $417 \times 2 = 834$
* $417 \times 60 = 25,020$
* $834 + 25,020 = 25,854$

9. $763 \times 22$
* $763 \times 2 = 1,526$
* $763 \times 20 = 15,260$
* $1,526 + 15,260 = 16,786$

10. $427 \times 59$
* $427 \times 9 = 3,843$
* $427 \times 50 = 21,350$
* $3,843 + 21,350 = 25,193$

11. $637 \times 55$
* $637 \times 5 = 3,185$
* $637 \times 50 = 31,850$
* $3,185 + 31,850 = 35,035$

12. $674 \times 49$
* $674 \times 9 = 6,066$
* $674 \times 40 = 26,960$
* $6,066 + 26,960 = 33,026$
