    40, 45,47 all have 4 tens

    31, 32 and 38 do not have 4 tens

  2. Elgin A.

    Platinum
    No because if she has 32p and she got 10p for her birthday she will have 42p so she wrong

  3. SAFA A.

    Safa things is 40

  4. Khadija B.

    Bronze: Khadija says this number could be 40 because it has four tens.

    Silver: jessica has the largest number because she have two tens and 9 ones (10+10+9=29). This is bigger than 27 ones which khadija has said is 27.

    Gold: yes habib is right because we are not changing the ones, just the tens.

    Platium: 10+10+10+10+10+10+10=70 which is 7 lots of 10. Khadija added 32 to 70 and ended up with 102p. Since there are 100 pennies in a pound, isla is right. she has more than a pound.

  5. Murtaza A.

    Bronze:
    It could be 40, 44, 47 or 49 because they all have 4 tens.

    It can’t be 30, 50, 10 because they are all tens but not 4 tens.

    Silver:
    Jessica had the most because she has 29 ones and faith only had 27 ones.

    Gold:
    Yes habib is right because the ones only change when you add ones but if you only add tens it stays the same.

    Platinum:
    Yes she is correct because she has 102p now and that is £1.02.

  7. Arham S.

    Four ones means 10+10+10+10=40
    20+20=40
    30+10=40
    35+7=42
    20+30=50

    Jessica has two tens and 9ones that means its 29 and its bigger than 27.

    Gold
    Yes it’s right.
    When we add ten to any number the ones always stay the same like,32+10=42
    50+10=60

    Platium
    She is right.she has more then £1.
    7lots of 10p =70p
    32+70= 102
    It’s more than £1.

  8. Mustafa A.

    Silver,
    Faith has more because Jessica has 2 ones and 9 ones and 9+2=11 so Jessica has more.

    1. Mustafa A.

      2 tens and 9 ones 20+9= 29

  9. Huzaifah J.

    Bronze 

    These numbers have four tens 40, 41, 42,43
,44,45,46,47,48,49
    Any number below 40 and any number above 49 can’t have four tens like 32 or 65
    Silver
    Jessica has the largest number because Faith has 27 ones and Jessica has 29 ones which is two ones more than Faith has.
    Gold 

    Yes Habib right, the number will go up by 10 keeping ones the same number

    52+10 = 62
    2 at the one position stay the same

    64+ 10=74

    4 at the one position stay the same

    Platinum 
Isla is right, she has total of £1.02
32p + 10+10+10+10+10+10+10 = 70p – total 102p

    So Isla has more than £1

    1. Huzaifah J.

      Platinum 
Isla is right, she has total of £1.02
 32p + 10+10+10+10+10+10+10 = 70p – total 102p
 So Isla has more than £1

    12
    silver
    jessica has a larger number because she has 2 tens which is twenty and 9 ones which is larger than 2 tens and 7 ones.
    gold
    when you add ten to a number the ones will stay the same because the tens are changing not the ones which means habib is correct.
    platimum
    isla is correct because 70 add 32 is 102
    which means £1.02

  12. Bilaal K.

    Bronze
    10+10+10+10=40
    20+20=40
    35+5=40

    40+7=47
    20+4=24
    44+10=54

    27+29=56
    Because there are 2 tens in each number we add those first to make 40.We then add 9+7=16 and then we add the two numbers to make 56.

    When you add tens to any number the ones always stay the same:
    26+10=36
    110+10=120
    39+10=49
    when these numbers are added to ten then the ones column stays the same.

  13. Ella K.

    Bronze
    41
    49
    46
    Silver
    Jessica has big number

  14. Huzaifa S.

    (Bronze)

    It could be 43, 46, 48.
    It can’t be 32, 55, 62.

    (Silver)
    Jassica has the largest number because she has two tens and nine ones so the whole number will become 29, whereas Faith had 27 which is two less then 29.
    Therefore 29 is bigger then 27.

    (Gold)

    Habib is correct because if you keep adding the number to 13 the ones stays the same. Examples:
    8+10=18
    5+ 10=15

  15. Kayla P.

    Bronze:

    The number could be 40 because that has 4 10’s: 10+10+10+10 = 40

    Or it could be: 44 because that has 4 10’s plus 2 1’s: 10 +10+10+10 + 1 + 1 +1+1 = 44

    Or it could be 46 because that has 4 10’s and 7 ones 10+10+10+10+1+1+1+1+1+1+1= 47

    The number can’t be 50 because that has 5 10’s = 10+10+10+10+10

    Or it can’t be 56 because that 5 10’s and 6 1’s = 10+10+10+10+10+1+1+1 +1+1+1= 56

    Or it can’t be 61 because that has 8 10’s and a two 1’s 10+10+10+10+10+10+10+10+10+1+1 = 82

    Silver:

    Jessica has the highest number because the total of her number is 29 because she has two 10’s and 9 1’s – 10+10+1+1+1+1+1+1+1+1+1 = 29

    Faith only has 27 because she has 27 1’s.

    Gold:

    Yes Habib is right. For example

    29+10 = 39 in this example 9 is in the one column which stays the same

    15+10 = 25 in this example 5 is in the one column which stays the same.

  17. Hannah B.

    Silver-
    Jessica has the largest number because 2 tens and 9 ones total 29 which is bigger than 27
    Gold-
    Yes, example 22+10=32 and 92+10=102
    Platinum
    Yes – 7 lots of 10p is 70p – add this to the 37p she already has equals 107p. As 100p equal £1, 107p is more than £1

  18. Adam O.

    Gold:
    Habib is right because if you 13 and you add 10, then the 1 changes to 2 but the 3 stays the same. The 3 is the “1s”.

    1. Adam O.

      Silver:
      Jessica has the bigger number because 2 10s is 20 and 20 +9 = 29. That is bigger that 27.

      1. Adam O.

        Bronze:
        Alex might have 40, 43, or 44, or 45, or 46

        1. Adam O.

          Platinum:
          Isla is correct because she has 32p+70p=102p that is the same as £1 and 2p.
