40, 45,47 all have 4 tens
31, 32 and 38 do not have 4 tens

Safa things is 40
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.
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.

10+10+10+10=40

Yes habib is right.
Example
10+4=14
10+8=18
10+6=16
10+9=19

Four ones means 10+10+10+10=40
20+20=40
30+10=40
35+7=42
20+30=50
Sliver
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.
Silver,
Faith has more because Jessica has 2 ones and 9 ones and 9+2=11 so Jessica has more.
2 tens and 9 ones 20+9= 29
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
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

70p+32p=102p

25
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
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.
Bronze
41
49
46
Silver
Jessica has big number
(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
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.
Bronze
It could be 40,41,42
It can’t be 31,32,33

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

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”.
