  1. 1.A is correct because 0.13 is greater than 0.09, 0.09 alone has 9 hundredths and 0.13 has 1 tenths and 3 hundredths and tenths are bigger than hundredths.
    2.B is correct because 0.10 is greater than 0.01, 0.01 alone has 1 hundredths whereas 0.10 has 1 tenths and 0 hundredths.
    3.C is incorrect because 0.33 is greater than 0.31, 0.31 alone has 3 tenths and 1 hundredths whereas 0.33 has 3 tenths and 3 hundredths.
    4.D is correct because 0.89 is greater than 0.79, 0.79 alone has 7 tenths and 9 hundredths whereas 0.89 alone has 8 tenths and 9 hundredths. :)

  2. Place value is important because it helps you understand the meaning of a number. If people just used numbers randomly, no one would know which numbers people meant. You need place value to understand the order of numbers as well.

      A is correct because 0.13 has 1 tenth and 3 hundredths. 0.9 has 9 tenths . 0.13 is bigger because the tenth are bigger value than the hundredths
      0.10 is bigger than 0.01 because 0.01 has 1 hundredths and 0.10 has 1tenth which means that the tenth is bigger than the hundredth.

  3. A) 0.13 > 0.09

    This number sentence is correct because 0.13 has 1 tenth
    and 3 hundredths,whereas 0.09 has no tenths but 9 hundredths.
    E.g 0.11 > 0.06.

    B) 0.01 0.33

    This is incorrect because 0.31 has 1 hundredth,but 0.33 has
    3 hundredths,meaning the numbers haven’t got greater. The number sentence should be 0.33 > 0.31.

    D) 0.79 < 0.89

    This is correct because 0.79 has 7 tenths and 9 hundredths,
    whereas 0.89 has 8 tenths and 9 hundredths.

    • Dylan please check your statements;
      0.31 has 3 tenths and 1 hundredths
      0.33 has 3 tenths and 3 hundredths

      Both have equivalent (same) ones and tenths, therefore you look in the hundredths column to see which has a higher value.

      Is 3 hundredth more or less than 1 hundredth?

  4. 0.09 is smaller than 0.13 because tenths are bigger than hundredths.0.9 has 9 hundreths ,whereas 0.13 has 13 tenths.E.g 0.3 is greater than 0.03.
    0.01is greater than 0.10.this correct because tenth is bigger then hundreths

    • Syed some good statements BUT you have written 0.13 has 13 tenths. How is this possible?
      Use your knowledge of place value columns to re-write the true value of each digit in 0.13

      H T O . Tth Hth
      0 . 1 3

  5. A)This number sentences is correct because 0.13 is a bigger number than 0.09 because tenths are a bigger place value than hundreths. A example Is that 0.9 is bigger than 0.09.
    B)This number sentence is incorrect because because 0.10 is greater than 0.01 because 0.10 has one tenths whereas 0.01 has one hundreth that means 0.10 is greater than 0.01. A example is that 0.11 is bigger than 0.02.

  6. This number sentence is correct because 0.13 has 13 tenths, whereas 0.09 has no tenths but has 7 hundreths.Tenths have a higher value than hudreths.This number sentence is correct because 0.10 has10 tenths, whereas 0.01has no tenths but has 10 hundreths.

    • Pranit good try, but you have confused the value of each digit within your number.
      HOW can you have 13 tenths? 10 tenths? 10 hundredths?
      One column= one digit

      H T O . Tth Hth
      0 . 1 2 (0 ones, 1 tenth, 2 hundredths)

      Re-write please.

  7. 1.This number sentence is correct because 0.13 has 1tenth and 3 hundredths, however 0.09 has 0 tenths and 9 hundredths and hundredths are smaller than tenths so this sentence is correct.
    2. This number sentence is correct because 0.10 has 1tenth but 0.01 has 0 tenths and 1hundreths and hundreths are smaller than tenths so it is correct.

  8. A.This number sentence is correct because 0.13 is a larger number than 0.09 for example 0.03 is greater than 0.01.
    B.This is correct because 0.10 is a greater number than 0.01 for example 0.11 is a larger number than 0.00.

    • HOW do you know Jay? You have not explained the importance of each place value. WHY is 0.13 more than 0.09?
      What does each digit represent?

      Same for your second explanation- needs to be redone please.

  9. A)This number sentence is correct because,0.13 has 1 tenth and 3 hundredth , whereas 0.09 has NO tenths but 9 hundredths. E.g 0.12>0.07. Tenths have a higher value than hundredths.
    B) This is correct because, 0.01 has 0 tenths and 1 hundredths , whereas 0.10 has 1 tenth. E.g 0.02< 0.10.

  10. 0.13 is bigger than 0.09 because tenths are bigger then hundredths.
    0.10 is not smaller than 0.01 because tenths are not smaller than hundredths.

  11. The number 0.13 is bigger than 0.09 because 0.13 has a tenth however 0.09 has no tenths. One tenth is higher value than 9hundreths.
    The number 0.01 is smaller than 0.10 because 0.01 has moved two spaces to the right and it should of done.0.10 is bigger than 0.01.

  12. 1. The first one is correct because 10 stands for 1 whole which is 1 tenths and any number after the tenths is hundrets 0.09 has no tenths whereas 0.13 has a tenths.
    2. The second one is correct because 0.01 is less than 0.10 because 0.01 has no tenths despite 0.10 does.

  13. A)the first one is correct because 10 stands for for 1 whole which is 1 tenths and any number after the tentths is hundred 0.09has no Tenths whereas 0.13 has a tenth

  14. A is correct because 0.13 is more than 0.09 however b is correct because 0.10 is more than 0.01. C is incorrect because 0.31 is smaller than 0.33 because the hundredth in 0.31 is smaller than 0.33.

  15. 1. The first one is correct because 10 is one whole witch is one tenth and any number after the tenth it is hundredth 0.09 has no tenths wheras 0.0 has one tenth
    2. The second one is correct because 0.01 has one tenth and 0.10 has 2 tenths
    However you are meant to move 2 space to the right

  16. 0.13 is bigger than 0.09 because tenths are bigger than hundredths so it’s right
    The second question is wrong because 0.10 is bigger than 0.01 so it’s wrong

  17. A is correct because 0.13 is more than 0.09 however the letter b is also correct because 0.10 is more than 0.01so if you do a column 0.10 would be more than 0.01.letter c is incorrect because 0.31 is less than 0.33 because in the ones column 3 is bigger than 1 so the answer would be incorrect

    • Redo
      The number sentence is correct because 0.13 has 13 tenth however 0.07 has 7 hundredths.
      The second number sentence is correct because 0.01 has 1 hundredths but o.10 doesn’t.

      • Zaid how can 0.13 have 13 tenths?
        There is only one tenths column how can you possibly have two digits within one place value column.
