a] Yes, because when you divide by ten you move 1 place to the right so if you divide again it’ll move 2 spaces to the right like your dividing by 100. Proof. E.g. 26/10=2.6/10=0.26 and 26/100=0.26.
10
a] 54/100=0.54 and 45/100=0.45

Smallest answer=0.11.
Biggest answer=0.66.
Great to support your great number sense with mathematical explanations. Happy Friday!

b) 48/100=0.48
6.
a) To get the correct answer you can move 2 places down on the Gattegno chart.
b) 92/100=0.92
c) 19/100=0.19

36/10/10=0.36
b) 91/10=9.1
91/100=0.91
91/10/10=0.91
9. Yes, I agree with Amir, that’s because if you divide twice by 10 is the same as dividing by 100.
10.
65/100=0.65 and 56/100=0.56
42/100=0.42 and 24/100=0.24
The biggest number I made is 0.65
The smallest number I made is 0.24
Some more great Maths work Alex, well done.
1a) 8 ones
b) 8: 100= 0.08
c) 8 hundredths
The counters moved to places to the right.
2a) 8 tens
b) 80:100=0.8
c) 8 tenths
The counters moved two places to the right.
3) To divide by 100 move the counters 2 places to the right.
4a) 0.03 b) 0.9 c) 0.05 d) 0.6 e) 50 f) 2
5) She should move the digit two places to the left when dividing by 100.
6a) I should move two places down.
b) 92:100= 0.92
c) 19: 100= 0.19
7a) 0.31 b) 0.60 c) 0.85 d) 1 e)0.29 f) 58 g)50 h) 100
8a) 3.6 0.36 0.36 b) 9.1 0.91 0.91
Dividing by 100 will have the same result as dividing by 10 twice.
9) Yes, each time when I divide by 10 I need to move the digit one place to the left. By dividing twice by 10 I will have to move the digit twice, the same number of places like in dividing by 100.
10) 12: 100= 0.12 and 21:100= 0.21
The greatest possible answer is 66.

b. 1. 91 ÷ 10 = 0.91
2. 91 ÷ 100 = 0.91
3. 91 ÷ 10 ÷ 10 = 0.91
9) Do you agree with Amir? – Yes because you can use your times tables and it will give you the full answer to get the hundred.
10) 1. 58 ÷ 100 = 0.58 and 0.58 ÷ 100 = 58
2. 24 ÷ 100 = 0.24 and 0.24 ÷ 100 = 24
