e.g. 32 / 5 = 6.4
when is the result a whole number?
when is the result as small as possible?
considering various families of 2-digit starting numbers:
- establish that there are four ways that you can obtain a result of 4(and four ways to obtain a result of 7)
- what happens for starting numbers that are multiples of 9?
- what relationship, for the 2-digit starting number, provides a result of (a) 5.5 (b) 3.25?
