Question 5 of 47intermediate🔧 ApplyFill in the Blanks4 marks

Let us fill in the table and observe the patterns. Complete the tables for: 2×12 \times 1,000 = ___; 5×15 \times 1,000 = ___; 10×110 \times 1,000 = ___; 20×120 \times 1,000 = ___; 3×53 \times 5,000 = ___; 8×38 \times 3,000 = ___; 5×75 \times 7,000 = ___. Also complete: 20×10020 \times 100 = ___; 40×50040 \times 500 = ___; 60×30060 \times 300 = ___; 600×30600 \times 30 = ___; 80×90080 \times 900 = ___; 70×60070 \times 600 = ___; 5×75 \times 7,000 = ___.

Correct Answer

2×12 \times 1,000 = 2,000; 5×15 \times 1,000 = 5,000; 10×110 \times 1,000 = 10,000; 20×120 \times 1,000 = 20,000; 3×53 \times 5,000 = 15,000; 8×38 \times 3,000 = 24,000; 5×75 \times 7,000 = 35,000. 20×10020 \times 100 = 2,000; 40×50040 \times 500 = 20,000; 60×30060 \times 300 = 18,000; 600×30600 \times 30 = 18,000; 80×90080 \times 900 = 72,000; 70×60070 \times 600 = 42,000; 5×75 \times 7,000 = 35,000.

Explanation

The chapter extends the pattern to multiplication by 1,000. When multiplying by 1,000, each digit moves three place values to the left, adding three zeros to the product.

Solution Steps

  1. Step 1: Multiply the non-zero digits

  2. Step 2: Count total zeros in both factors

  3. Step 3: Add zeros to the product

  4. Step 4: Place in correct columns (TTh, Th, H, T, O)
