    A) The mistake is that she hasn’t moved the 40 to the right 1once to make the answer.
    B)
    48/100=0.48

    1
    a] 8 ones
    b] 8/100=0.08
    c] 8 hundredths

    2
    a] 8 tens
    b] 80/100=0.8
    c] 8 tenths

    3
    a] 2 places to the right.

    4
    a] 3/100=0.03
    b] 90/100=0.9
    c] 0.05
    d] 0.6
    e] 5
    f] 2

    5
    a] Her mistake was stupid. She just didn’t move the tens 2 to the right.
    b] 48/100=4.8

    6
    a] You just move 2 spaces downwards.
    b] 92/100=0.92
    c] 19/100=0.19

    7
    a] 31/100=0.31
    b] 60/100=0.60
    c] 85/100=0.85
    d] 1
    e] 29/100=0.29
    f] 58
    g] 50
    h] 10

    8
    a] 36/10=3.6
    b] 36/100=0.36
    c] 36/10/10=0.36
    d] 91/10=9.1
    e] 91/100=0.91
    f] 91/10/10=0.91

    9
    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
    b] 31/100=0.31 and 13/100=0.13
    Smallest answer=0.11.
    Biggest answer=0.66.

    1.
    a) 8 ones
    b) 8/100=0.08
    c) 8 hundredths
    If we divide by 100, we move the counters by 2 places to the right

    2.
    a) 8 tens
    b) 80/100=0.8
    c) 8 tenths

    3.
    To divide by 100 you move the counters 2 places to the right.

    4.
    a) 3/100=0.03
    b) 90/100=0.9

    d) 0.6=60/100
    e) 50/100=0.5
    f) 0.02=2/100

    5.
    a) Dora made a mistake and moved only one of the counters by 2 places, leaving 4 tens in the same place, which is incorrect.
    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

    7.
    a) 31/100=0.31
    b) 60/100=0.6
    c) 0.85=85/100

    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

    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.
    The smallest possible answer is 11.
