Text Solution

AI Generated Solution

The correct Answer is:
To estimate the product of 38 and 63 by rounding each number to the nearest ten, we can follow these steps: ### Step 1: Round 38 to the nearest ten. - Look at the digit in the ones place of 38, which is 8. - Since 8 is greater than 5, we round up. - Add 1 to the digit in the tens place (3), which gives us 4. - Replace the ones place with 0. - Therefore, 38 rounded to the nearest ten is **40**. ### Step 2: Round 63 to the nearest ten. - Look at the digit in the ones place of 63, which is 3. - Since 3 is less than 5, we round down. - The digit in the tens place (6) remains the same. - Replace the ones place with 0. - Therefore, 63 rounded to the nearest ten is **60**. ### Step 3: Multiply the rounded numbers. - Now, we multiply the rounded values: 40 and 60. - Calculate: - \( 40 \times 60 = 2400 \). ### Final Answer: The estimated product of 38 and 63 is **2400**. ---
