Rounding To Tens And Hundreds Quiz - Quiz

Quiz Preview

  • 2. 

    Round 253 to the nearest tens.

    • 240

    • 300

    • 250

    • 200

    Correct Answer
    A. 250
    Explanation
    To round 253 to the nearest tens, we look at the ones digit, which is 3. Since 3 is less than 5, we round down. Therefore, the tens digit remains the same, and the ones digit becomes 0. Hence, the number 253 rounds to 250.

    Rate this question:

  • 3. 

    What is 296 rounded to the nearest hundreds?

    • 300

    • 200

    • 290

    • 260

    Correct Answer
    A. 300
    Explanation
    296 rounded to the nearest hundreds is 300 because when rounding to the nearest hundreds, we look at the tens digit. If it is 5 or greater, we round up, and if it is less than 5, we round down. In this case, the tens digit is 9, which is greater than 5, so we round up to the next hundred, which is 300.

    Rate this question:

  • 4. 

    What is 77 rounded to the nearest 10?

    • 70

    • 60

    • 50

    • 80

    Correct Answer
    A. 80
    Explanation
    The number 77 is closer to 80 than to any other multiple of 10. When rounding to the nearest 10, if the number is exactly halfway between two multiples of 10, it is rounded up to the nearest even multiple of 10. Therefore, 77 is rounded to 80.

    Rate this question:

  • 5. 

    Which of the following numbers is a weak number?

    • 9

    • 5

    • 4

    • 8

    Correct Answer
    A. 4
    Explanation
    A weak number is a number that can be expressed as the sum of its own digits raised to the power of the number of digits. In this case, 4 is a weak number because it has only one digit, and 4^1 equals 4.

    Rate this question:

  • 6. 

    What is 781 rounded to the nearest tens?

    • 700

    • 710

    • 800

    • 780

    Correct Answer
    A. 780
    Explanation
    The number 781, when rounded to the nearest tens, would be 780. This is because the digit in the ones place, which is 1, is less than 5. Therefore, we round down to the nearest tens, which is 780.

    Rate this question:

  • 7. 

    Which of the following numbers is a strong numbers?

    • 0

    • 2

    • 5

    • 3

    Correct Answer
    A. 2
    Explanation
    A strong number is a number whose sum of the factorials of its digits is equal to the original number.
    Let's check each option:
    0: 0! = 1 (0 is not a strong number)
    2: 2! = 2 (2 is a strong number)
    5: 5! = 120 (5 is not a strong number)
    3: 3! = 6 (3 is not a strong number)
    Therefore, the only strong number among the options is 2.

    Rate this question:

  • 8. 

     Round 817 to the nearest hundreds.

    • 810

    • 800

    • 820

    • 900

    Correct Answer
    A. 800
    Explanation
    To round 817 to the nearest hundreds, we look at the tens digit, which is 1. Since it is less than 5, we round down the hundreds digit, which is 8, to the nearest hundreds. Therefore, the correct answer is 800.

    Rate this question:

  • 9. 

    What digit do you need to look at to round 462 to the nearest tens?

    • 4

    • 6

    • 2

    • None of these

    Correct Answer
    A. 2
    Explanation
    To round 462 to the nearest tens, we need to look at the digit in the units place, which is 2. If the units digit is 5 or greater, we round the tens digit up. If the units digit is less than 5, we keep the tens digit the same. In this case, 2 is less than 5, so we keep the tens digit (6) the same. Therefore, 462 rounded to the nearest tens is 460.

    Rate this question:

  • 10. 

    If rounding 1,208 to the nearest hundred, what place value would you look at to make your decision?

    • Ones

    • Tens

    • Hundreds

    • None of these

    Correct Answer
    A. Tens
    Explanation
    To round 1,208 to the nearest hundred, we need to look at the digit in the tens place, which is 0. If the tens digit is 5 or greater, we round the hundreds digit up. If the tens digit is less than 5, we keep the hundreds digit the same. In this case, 0 is less than 5, so we keep the hundreds digit (2) the same. Therefore, 1,208 rounded to the nearest hundred is 1,200.
