    1)False because it is not 1900.
    2)False because the hundreds are not over 1500.
    3)False because the hundreds are not over 4500.
    4)False because the tens are too small to make it bigger.

      Make sure you explain your answers and reasons for this.

      For example:

      1) This is false.
      This reason for this is that the two 100s that lie on either side of 1543 is 1500 and 1600. Since 1543 is less than 1550, this would mean that it is closer to 1500. The answer is 1500 and it cannot be 2000 as this is not the closest 100!

    The first one is false because the number is.1543 and you were supposed to round to the nearest 100 but it is rounded to the nearest 1000 and the real answer is 1500.
    The second one is false because the number is 1096 and you were supposed to round it to the nearest 10 but it was rounded to the nearest

  6. Fathiya Mohammed

    1 False because 4 is bellow 5 so it is false
    2. False because it is 1100 because 100 + 1000 is 1100
    3.False because 76 to the nearest 1000 is 0 and 4000 +0 is 4000
    4.False because 45 to the nearest 100 is 0 and 7000 to the nearest 100 is 0 so 7000 add 0 is 7000

  9. Murran Masterson

    The first one is false because it says round to the nearest 100 when he has rounded to the nearest 1000.
    The second one is false because it says round to the nearest 10.

  10. Saniya Mahmood

    1. 1543 rounded to the nearest 100 is 2000
    This statement is not true because 40 is under 50

  11. Ismail Ali

    1)1543 rounded to the nearest 100 is not 2000 because if you round 1543 to the nearest 100 it would be 1500 and BOB rounded 1543 to the nearest 1000.

    2)1096 rounded to the nearest 10 is not 2000 because 1096 rounded to the nearest 10 is 1100 not 2000.

    3)4076 rounded to the nearest 1000 is not 5000 because 4076 rounded to the nearest is 4000.

    4)7045 rounded to the nearest 100 is not 7100 because 45 is not higher than 50 and because 7045 rounded to the nearest 100 is 7000.

    5)It is true

  12. Leila Dadkhah

    1) This is false because it is not rounding to 1000 it is 100
    2)This is true because the units are over 4

  13. Murtaza Ali

    1:False,because 43 rounded to the nearest 10 is 40 and 40 to the nearest 100 is 0 that means the nearest 100 to 1543 is 1500.
    2:False because 96 to the nearest 10 is 100 so 1000 add 100 is 1100.
    3:False,because 76 to the nearest 1000 is 0 and 4000 add 0 is 4000.
    4:False,45 to the nearest 100 is 0 and 7000 to the nearest 100 is 0 so 7000 add 0 is 7000.
