Answer 2

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
