    • 5,000

    Correct Answer
    A. 6,000
    Explanation
    When rounding 5,673 to the nearest 1,000, we look at the digit in the thousands place, which is 5. Since this digit is greater than or equal to 5, we round up. Therefore, the nearest 1,000 to 5,673 is 6,000.

    • 9,000

    • 10,000

    Correct Answer
    A. 8,000
    Explanation
    To round to the nearest thousand, look at the hundreds digit. If it's 5 or greater, round up. If it's less than 5, round down. In this case, the hundreds digit is 4, so we round down to 8,000.

    • 500

    • 420

    • 400

    Correct Answer
    A. 400
    Explanation
    When rounding 416 to the nearest 100, we look at the digit in the tens place, which is 1. Since 1 is less than 5, we round down. Therefore, 416 rounded to the nearest 100 is 400.

    27 rounded to the nearest 10 would be ?

    • 20

    • 25

    • 30

    Correct Answer
    A. 30
    Explanation
    When rounding a number to the nearest 10, we look at the digit in the ones place. If it is 5 or greater, we round up to the next multiple of 10. In this case, the digit in the ones place is 7, which is greater than 5. So, we round up to the next multiple of 10, which is 30.

    Rate this question:

    456 rounded to the nearest 100 would be ?

    • 400

    • 500

    • 460

    Correct Answer
    A. 500
    Explanation
    When rounding 456 to the nearest 100, we look at the digit in the tens place, which is 5. Since 5 is greater than or equal to 5, we round up the hundreds digit to the next whole number, which is 5. Therefore, 456 rounded to the nearest 100 would be 500.

    Rate this question:

  • 8. 

    87 - 19 =

    Correct Answer
    68
    Explanation
    The given expression is a subtraction problem where we subtract 19 from 87. When we subtract 19 from 87, we get the result as 68.

    Rate this question:

  • 9. 

    634 - 541 =

    Correct Answer
    93
    Explanation
    The given question requires subtracting 541 from 634. When subtracting, we start from the rightmost digit and subtract each corresponding digit. In this case, 4 minus 1 equals 3, 3 minus 4 is -1, and 6 minus 5 is 1. Since we have a negative result in the middle, we can borrow 1 from the leftmost digit, resulting in 5 minus 4 equals 1. Therefore, the correct answer is 93.

    809 rounded to the nearest 100 would be ? 

    • 810

    • 800

    • 900

    Correct Answer
    A. 800
    Explanation
    809 rounded to the nearest 100 would be 800 because when rounding to the nearest 100, we look at the tens digit. If the tens digit is 5 or more, we round up to the next hundred. In this case, the tens digit is 0, which is less than 5, so we round down to the previous hundred, which is 800.

    A chicken farmer collected 412 eggs in March and 596 in April. How many more eggs were collected in April?   Round your numbers to the nearest 10.

    • 80 eggs

    • 180 eggs

    • 380 eggs

    • 980 eggs

    Correct Answer
    A. 180 eggs
    Explanation
    In March, the chicken farmer collected 412 eggs. In April, the farmer collected 596 eggs. To find out how many more eggs were collected in April, we subtract the number of eggs collected in March from the number of eggs collected in April. 596 - 412 = 184. However, we need to round the numbers to the nearest 10, so the answer is 180 eggs.

    Lindsey wants to estimate how many comic books she and her friends have. She has 2,169, Les has 6,131 and Neil has 2,702.  Round to the nearest tens.    They have a total of _____________ comic books.

    Correct Answer
    11,000
    11000
    11 000
    Explanation
    Lindsey has 2,169 comic books, Les has 6,131 comic books, and Neil has 2,702 comic books. To estimate the total number of comic books, we need to round each individual number to the nearest tens. Rounding 2,169 to the nearest tens gives us 2,170, rounding 6,131 gives us 6,130, and rounding 2,702 gives us 2,700. Adding these rounded numbers together, we get a total of 2,170 + 6,130 + 2,700 = 11,000 comic books.

    A lorry driver makes journeys of 78 miles, 215 miles, 409 miles and 108 miles. What is the total distance travelled?  Round to the nearest tens.  Round to the nearest 10.

    • 710 miles

    • 610 miles

    • 810 miles

    • 1,010 miles

    Correct Answer
    A. 810 miles
    Explanation
    To find the total distance traveled, you simply add up the individual distances:
    78 miles + 215 miles + 409 miles + 108 miles = 810 miles
    So, the total distance traveled is 810 miles when rounded to the nearest ten. Therefore, the correct answer is:
    810 miles
