Platium
Bronze: 40,41,42,43,44 all these numbers have 4 tens.
The numbers which can’t be are 50,60,70,80,90.
Silver:Jessica has the largest number as Jessica has 29 and Faith has 27 ones which is a small number than Jessica.
Gold: Habib says right if we add tens to any number the ones stays the same.
Like if we add one ten to 14 it will be 24 so the ones will be the same the 4 ones are same.
If we add a ten in 22 the two ones stay the same and there will be three tens.
Platium:
Isla is right she has more than one pound because she has 7 lots of 10p=70p and she already has 32p so 70p+32p=£1.02
Platinum:
Isla is correct because 70p+32p=102p
102p is the same as £1.02p
£1.02p is bigger than £1.
Bronze: 40, 42, 44
It cannot be, 20. 12. 1
Silver: Jessica has the largest number, she has 29
Gold: Yes they remain the same. e.g 1 ten plus 2 ones= 12 1. tens plus 4= 14

Super Maths, Safiyyah.
Great explanations 👍🏻
(1) Jessica has the largest number (20+9,+29) and faith has 27.
(2) 41, 42, 43, it can’t be outside 40 to 49 for example 31, 61, and 71.
When you add multiple of ten (10,20,30,40 50,60,70,80,90. ) you are increasing its the value in the tens column without affecting the ones column. Example if add 10+35 you get 45. The one digit(5) remains the same .
Platinum ( 32p.7 lots of 10p
10+20+30+10=70. 70+32=102.
£1.02p. She’s correct.
Because she has 1 and 02pence.
Bronze
41 , 42, 43, 44
Number can’t be 50, 60, 70 because they don’t come within 40s.
Silver
Jessica because she has more than faith.
Gold
Yes because if you add 32+10 =42 42+10=52
Habib is right because when you add ten only the tens place changes
Bronze
It can be 41 43 and 45
It can’t be 31 23 11 because they don’t have four tens.
Silver
Jessica has the largest number because her 2 tens and one 9s equals 29. Faith is 27 ones equals 27.
Gold
Habib is right because 11 plus ten equals 21
21 plus 10 equals 31
An
And 31 plus 10 equals 41 and so on.
Platinum
Isla is correct because 7 tens equals 70 and 32p totals together 1 pound and 2p.
Bronze:
Numbers with tens are 40, 41, 42, 43. Number 4 is in the tens place for all numbers from 40 to 49
Examples for numbers that cannot have 4 in tens place are 10, 20, 50
Silver:
Faith has 27 ones = 27
Jessica has 2 tens (10+10 = 20) and 9 ones = 9. That is 20 + 9 = 29
27 < 29. Therefore, Jessica has the largest number.
Gold:
Yes, Habib is right, when 10 is added to any number, the number in ones place always remains the same, because any number added to zero will give the same number.
Example: 11+ 10 = 21, the number in ones place is the same, which is 1 when added to 10.
Platinum:
Isla has 32p
She got 7 lots of 10p, (10p+10p+10P+10p+10P+10p+10P = 70p)
Now she has 32p + 70P, which makes it 102p
100p = £1
102p = £1 + 2p
Isla is correct, she has more than £1.
Well done, Ameya!
PLATINUM
Isla is correct, because she has 102Pence which is greater than £1.(100 pence is equal to £1)
32P
7 lots of 10 = 70P
32P + 70P = 102P , which greater than 100P (£1) so she is correct.
Thank You.
Silver
Jessica has the largest number because
Faith has :
27 one’s = 27
Jessica has:
Two tens = 20
Nine ones= 9
20 +9 =29
Faith has 27 and Jessica has 29
29 is larger than 27
Jessica has the largest number
1. 10+10+10+10=40
20+20=40
30+10=40
41,42
2.Faith has 27 and Jessica has 29 so she has 2 more.
3. yes because 15+10= 25 the 5 stays the same

Great work, Ameera
Bronze
41, 42, 43 it cannot be outside 40 to 49 for example 31, 61 and 71.
Silver
Jessica has the largest number because she have two tens (10+10 = 20). 9 ones (20+9=29). Jessica have the number 29 and Faith have 27.
Gold
Yes he is right because when you add tens to any number, the ones digit remain the same. When you add multiple of ten (10, 20, 30, 40, 50, 60, 70, 80, 90) you are increasing its place value in the tens column without affecting the ones column. For example if you add 10 to 35 you get 45. The ones digit (5) remains the same.
Platinum
32p. 7 lots of 10p. 10+10+10+10+10+10+10=70. 70+32=102. £1.02p. She is correct.

The numbers that it could be is – 40 42 49
The numbers it can’t be is – 37 53 68
Silver
Jessica has the larger number. She has two tens, which is similar to 20, and 9 ones, making her total 29. Faith has 27 ones, which is less than Jessica’s total.
Gold
Habib’s statement is correct. When you add ten to any number, the ones place may stay the same. For example: 10 + 10 = 20 the ones place did stay the same, 11 + 10 = 21 the ones place did stay the same and 19 + 10 = 29 the ones place did stay the same.
Platinum
Yes, Isla is correct
32p + 70p = 102p

Silver
Jessica has the largest number because she has 20 tens and 9 ones which is 29. 29 is largest number then 27.
