\frac{1}{4}-\frac{15}{100}
Whakahekea te hautanga \frac{25}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
\frac{1}{4}-\frac{3}{20}
Whakahekea te hautanga \frac{15}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{5}{20}-\frac{3}{20}
Ko te maha noa iti rawa atu o 4 me 20 ko 20. Me tahuri \frac{1}{4} me \frac{3}{20} ki te hautau me te tautūnga 20.
\frac{5-3}{20}
Tā te mea he rite te tauraro o \frac{5}{20} me \frac{3}{20}, me tango rāua mā te tango i ō raua taurunga.
\frac{2}{20}
Tangohia te 3 i te 5, ka 2.
\frac{1}{10}
Whakahekea te hautanga \frac{2}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
