1) They are both correct as Lucas done 2100 divided by 10 and divided it by 10 again that equals 21 and 10*10=100 and if you do 2100 divided by 100 it equals to 21, Sienna said if you move 2100 two spaces to the right you’ll get the answer and she is correct as whenever we divide we move two spaces to the right.

 

2) Only one of George’s calculations are correct↓

1110÷10= 111

1100÷10=110

10100÷100= 101

111000÷10÷10=111

The pictures are quite blurry so you may not see them and I only took pictures of half of what we done as my next page was quite messy.
