Explanation

The chapter applies multiplication to find total pencils needed. 465 students need 2 pencils each: 465×2465 \times 2 = 930 pencils. Breaking 465 into 400 + 60 + 5: 400×2400 \times 2 = 800, 60×260 \times 2 = 120, 5×25 \times 2 = 10. Total = 800 + 120 + 10 = 930 pencils.

Solution Steps

  1. Step 1: Total pencils = 465 students × 2 pencils per student

  2. Step 2: Break 465 into 400 + 60 + 5

  3. Step 3: 400×2400 \times 2 = 800 pencils

  4. Step 4: 60×260 \times 2 = 120 pencils

  5. Step 5: 5×25 \times 2 = 10 pencils

  6. Step 6: Total = 800 + 120 + 10 = 930 pencils
