Apply Euclid's lemma and prime factorisation for HCF-LCM.
Prove root 2, 3 and 5 irrational.
Test decimal expansions for terminating patterns.

A useful tip

Terminating decimals need denominators of only 2s and 5s after simplification: 13/40 terminates, 7/30 repeats. Prime-factor the denominator to predict.
