\frac{9}{10}-\frac{3}{4}
Me tahuri ki tau ā-ira 0.9 ki te hautau \frac{9}{10}.
\frac{18}{20}-\frac{15}{20}
Ko te maha noa iti rawa atu o 10 me 4 ko 20. Me tahuri \frac{9}{10} me \frac{3}{4} ki te hautau me te tautūnga 20.
\frac{18-15}{20}
Tā te mea he rite te tauraro o \frac{18}{20} me \frac{15}{20}, me tango rāua mā te tango i ō raua taurunga.
\frac{3}{20}
Tangohia te 15 i te 18, ka 3.
