Construct a times-15 table. How can we find 1×15,2×15,…1 \times 15, 2 \times 15, \ldots with this?

1×15=____6×15=____1 \times 15 = \_\_\_\_ \quad 6 \times 15 = \_\_\_\_ 2×15=____7×15=____2 \times 15 = \_\_\_\_ \quad 7 \times 15 = \_\_\_\_ 3×15=____8×15=____3 \times 15 = \_\_\_\_ \quad 8 \times 15 = \_\_\_\_ 4×15=____9×15=____4 \times 15 = \_\_\_\_ \quad 9 \times 15 = \_\_\_\_ 5×15=____10×15=____5 \times 15 = \_\_\_\_ \quad 10 \times 15 = \_\_\_\_
Correct Answer

1×15=151 \times 15 = 15, 2×15=302 \times 15 = 30, 3×15=453 \times 15 = 45, 4×15=604 \times 15 = 60, 5×15=755 \times 15 = 75, 6×15=906 \times 15 = 90, 7×15=1057 \times 15 = 105, 8×15=1208 \times 15 = 120, 9×15=1359 \times 15 = 135, 10×15=15010 \times 15 = 150

Explanation

The times-15 table can be constructed by splitting 15 as 10+510 + 5. For example, 4×15=4×10+4×5=40+20=604 \times 15 = 4 \times 10 + 4 \times 5 = 40 + 20 = 60. Each successive product increases by 15.

Solution Steps

  1. Step 1: For each multiplication, split 15 as 10+510 + 5

  2. Step 2: Multiply the number by 10 and by 5 separately

  3. Step 3: Add the two results
