Multiply using partial products. Fill in the missing numbers.

648 × 2 1,200 80 +

Solution

To solve the multiplication problem using partial products, we break down the number 648 into hundreds, tens, and units, then multiply each by 2. Step 1: Break down 648 into parts: 600, 40, and 8. Step 2: Multiply each part by 2. \[ 600 \times 2 = 1200 \] \[ 40 \times 2 = 80 \] \[ 8 \times 2 = 16 \] Step 3: Add the partial products together. \[ 1200 + 80 + 16 = 1296 \] Thus, the missing numbers are 16 and 1296.
