\frac{21}{10}+\frac{2\times 5+3}{5}
Tāpirihia te 20 ki te 1, ka 21.
\frac{21}{10}+\frac{10+3}{5}
Whakareatia te 2 ki te 5, ka 10.
\frac{21}{10}+\frac{13}{5}
Tāpirihia te 10 ki te 3, ka 13.
\frac{21}{10}+\frac{26}{10}
Ko te maha noa iti rawa atu o 10 me 5 ko 10. Me tahuri \frac{21}{10} me \frac{13}{5} ki te hautau me te tautūnga 10.
\frac{21+26}{10}
Tā te mea he rite te tauraro o \frac{21}{10} me \frac{26}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{47}{10}
