my way:   ((54329)/(2467))≈((543.3)/(24.67)) ≈ ((543.3+(1/3)×22)/(24.67+(1/3)))  ≈((550.6)/(25))≈((2202.4)/(100))=22.024
$${my}\:{way}: \\ $$$$\:\frac{\mathrm{54329}}{\mathrm{2467}}\approx\frac{\mathrm{543}.\mathrm{3}}{\mathrm{24}.\mathrm{67}}\:\approx\:\frac{\mathrm{543}.\mathrm{3}+\frac{\mathrm{1}}{\mathrm{3}}×\mathrm{22}}{\mathrm{24}.\mathrm{67}+\frac{\mathrm{1}}{\mathrm{3}}} \\ $$$$\approx\frac{\mathrm{550}.\mathrm{6}}{\mathrm{25}}\approx\frac{\mathrm{2202}.\mathrm{4}}{\mathrm{100}}=\mathrm{22}.\mathrm{024}\: \\ $$
