Multiplying Fractions

It’s a more straightforward operation than adding. I ultimately end up saying “top times top, bottom times bottom”.  That works, but why does it work, when it doesn’t work for adding fractions?

This might help a bit…  Reinforces the notion that of means times, i.e. when I buy 4 bags of crisps at 30p each, they cost 4 x 30p.  Same for fractions, e.g. 1/5 of 2/3
