Answer:
3 1/2
Investigating the number of 2's that can be fitted into 7
Consider 2 +2 + 2 + 2 = 8
this is too big so too many 2's
Consider
2 + 2+ 2 = 6
this will fit into 7 but the remainder is 7-6=1
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now lets start again but in a different way.
Split 7 up into 6 + 1
So 7 ÷ 2 is the same as ... ( 6 + 1 ) ÷ 2
which is the same as: ... 6 ÷ 2 + 1 ÷ 2
which is the same as ...
6 2 + 1 2
which is the same as ...
3 + 1 2 → 3 1 2
