Whakahekea te hautanga \frac{15}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{1660}{20}-\frac{3}{20}
Me tahuri te 83 ki te hautau \frac{1660}{20}.
\frac{1660-3}{20}
Tā te mea he rite te tauraro o \frac{1660}{20} me \frac{3}{20}, me tango rāua mā te tango i ō raua taurunga.
\frac{1657}{20}
Tangohia te 3 i te 1660, ka 1657.
