Kua tāruatia ki te papatopenga
\frac{1}{2}+\frac{3}{20}+\sqrt{5}
Me tahuri ki tau ā-ira 0.15 ki te hautau \frac{15}{100}. Whakahekea te hautanga \frac{15}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{10}{20}+\frac{3}{20}+\sqrt{5}
Ko te maha noa iti rawa atu o 2 me 20 ko 20. Me tahuri \frac{1}{2} me \frac{3}{20} ki te hautau me te tautūnga 20.
\frac{10+3}{20}+\sqrt{5}
Tā te mea he rite te tauraro o \frac{10}{20} me \frac{3}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{13}{20}+\sqrt{5}
Tāpirihia te 10 ki te 3, ka 13.
