Multiply using partial products. Fill in the missing numbers.

19 × 3

• 27

Solution

To multiply using partial products, we will break down the multiplication of 19 by 3. First, separate 19 into its tens and ones: 19 = 10 + 9 Next, multiply each part by 3: Multiply the tens part: \[ 10 \times 3 = 30 \] Multiply the ones part: \[ 9 \times 3 = 27 \] Now, add the partial products together: \[ 30 + 27 = 57 \] So, the missing numbers are 30 and 57.
