Lesson 3: Multiply three- and four-digit numbers by one-digit numbers applying the standard algorithm. — Practice Questions

  1. 1. When calculating $4 \times 28$, you first multiply $4 \times 8 = 32$. The digit 2 is written in the ones place. What digit is carried to the tens place? \n\n___

  2. 2. In the standard multiplication algorithm, what does a 'carried' digit from the ones column to the tens column represent?

    • A. The number of tens regrouped from the ones place.
    • B. The final digit of the answer.
    • C. A number to be subtracted.
    • D. The total sum of the digits.
  3. 3. To solve $5 \times 132$, you first multiply $5 \times 2 = 10$. A 1 is carried to the tens place. Next, you multiply $5 \times 3 = 15$ and add the carried 1 to get 16. What digit is carried to the hundreds place? \n\n___

  4. 4. When calculating $6 \times 45$, the first step is $6 \times 5 = 30$. Which digit should be carried to the tens column?

    • A. 0
    • B. 3
    • C. 5
    • D. 30
  5. 5. When multiplying $3 \times 182$, you first handle the ones place. For the tens place, you multiply $3 \times 8 = 24$ tens. What digit is carried to the hundreds place from this step? \n\n___

  6. 6. In the problem $8 \times 153$, you eventually multiply the tens digits: $8 \times 5 = 40$ tens. A '4' is carried to the hundreds column. What is the value of this carried '4'?

    • A. 4 ones
    • B. 4 tens
    • C. 4 hundreds
    • D. 4 thousands
  7. 7. To calculate $7 \times 39$, you first multiply $7 \times 9 = 63$. The digit 3 is written in the ones place, and the digit ___ is carried to the tens place.

  8. 8. When calculating $4 \times 221$ using the standard algorithm, is it necessary to carry a digit from the ones place to the tens place?

    • A. Yes
    • B. No
  9. 9. When calculating $178 \times 5$, what is the first operation performed in the standard algorithm?

    • A. Multiply $5 \times 1$
    • B. Multiply $5 \times 8$
    • C. Multiply $5 \times 7$
    • D. Add $1 + 7 + 8$
