Explanation

The chapter applies multiplication to find the total. 15 rows with 8 children each: 15×815 \times 8 = 120 children. Using the decomposition method: 10×810 \times 8 = 80 and 5×85 \times 8 = 40. Total = 80 + 40 = 120 children.

Solution Steps

  1. Step 1: Total children = 8 children × 15 rows

  2. Step 2: Break 15 into 10 + 5

  3. Step 3: 10×810 \times 8 = 80 children

  4. Step 4: 5×85 \times 8 = 40 children

  5. Step 5: Total = 80 + 40 = 120 children
