DAY 43

Comment

This can be solved by applying rules for operating with fractions, but a less formal approach should also work.
For a start, the answer will be greater than 1 because 1/20 is smaller than 1/5,
which prompts questions like 'how many times does 1/20 fit into 1/5?' or 'how many times smaller is 1/20 than 1/5 ?'.

Answer

4.

Lenny Seynt, Leominster:
I learnt that dividing by 1/20 is the same as multiplying by 20/1.
1/5 times 20/1 = 20/5 = 4.
