Key methods
Simplifying: divide numerator and denominator by their HCF.
\(\dfrac{12}{16}\) — HCF of 12 and 16 is 4 — divide both: \(\dfrac{12\div4}{16\div4}=\dfrac{3}{4}\)
Equivalent fractions: multiply or divide both parts by the same number.
\(\dfrac{3}{4}=\dfrac{3\times5}{4\times5}=\dfrac{15}{20}\)
