\frac{3}{4}+\frac{2}{4}-\frac{1}{5}
Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri \frac{3}{4} me \frac{1}{2} ki te hautau me te tautūnga 4.
\frac{3+2}{4}-\frac{1}{5}
Tā te mea he rite te tauraro o \frac{3}{4} me \frac{2}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{5}{4}-\frac{1}{5}
Tāpirihia te 3 ki te 2, ka 5.
\frac{25}{20}-\frac{4}{20}
Ko te maha noa iti rawa atu o 4 me 5 ko 20. Me tahuri \frac{5}{4} me \frac{1}{5} ki te hautau me te tautūnga 20.
\frac{25-4}{20}
Tā te mea he rite te tauraro o \frac{25}{20} me \frac{4}{20}, me tango rāua mā te tango i ō raua taurunga.
\frac{21}{20}
Tangohia te 4 i te 25, ka 21.
