Horizontally Arranged Multiplying (1 to 7) by 3 (25 Questions ... - Free Printable

To solve this worksheet, we need to find the product of each multiplication problem. Since every problem involves multiplying by 3, we can think of it as adding the number to itself three times (or just knowing the 3 times table).

Let's go through the list column by column, from top to bottom.

Left Column:
1. 7 x 3: $3 + 3 + 3 + 3 + 3 + 3 + 3 = 21$
2. 2 x 3: $3 + 3 = 6$
3. 4 x 3: $3 + 3 + 3 + 3 = 12$
4. 5 x 3: $3 + 3 + 3 + 3 + 3 = 15$
5. 3 x 3: $3 + 3 + 3 = 9$
6. 6 x 3: $3 + 3 + 3 + 3 + 3 + 3 = 18$
7. 1 x 3: Just 3.
8. 2 x 3: $3 + 3 = 6$
9. 7 x 3: $3 + 3 + 3 + 3 + 3 + 3 + 3 = 21$
10. 1 x 3: Just 3.
11. 6 x 3: $3 + 3 + 3 + 3 + 3 + 3 = 18$
12. 3 x 3: $3 + 3 + 3 = 9$
13. 4 x 3: $3 + 3 + 3 + 3 = 12$

Right Column:
1. 5 x 3: $3 + 3 + 3 + 3 + 3 = 15$
2. 4 x 3: $3 + 3 + 3 + 3 = 12$
3. 1 x 3: Just 3.
4. 2 x 3: $3 + 3 = 6$
5. 5 x 3: $3 + 3 + 3 + 3 + 3 = 15$
6. 6 x 3: $3 + 3 + 3 + 3 + 3 + 3 = 18$
7. 3 x 3: $3 + 3 + 3 = 9$
8. 7 x 3: $3 + 3 + 3 + 3 + 3 + 3 + 3 = 21$
9. 2 x 3: $3 + 3 = 6$
10. 3 x 3: $3 + 3 + 3 = 9$
11. 4 x 3: $3 + 3 + 3 + 3 = 12$
12. 5 x 3: $3 + 3 + 3 + 3 + 3 = 15$
