Kua tāruatia ki te papatopenga
\frac{2+1}{2}+2.2\times \frac{2}{11}
Whakareatia te 1 ki te 2, ka 2.
\frac{3}{2}+2.2\times \frac{2}{11}
Tāpirihia te 2 ki te 1, ka 3.
\frac{3}{2}+\frac{11}{5}\times \frac{2}{11}
Me tahuri ki tau ā-ira 2.2 ki te hautau \frac{22}{10}. Whakahekea te hautanga \frac{22}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{3}{2}+\frac{11\times 2}{5\times 11}
Me whakarea te \frac{11}{5} ki te \frac{2}{11} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{3}{2}+\frac{2}{5}
Me whakakore tahi te 11 i te taurunga me te tauraro.
\frac{15}{10}+\frac{4}{10}
Ko te maha noa iti rawa atu o 2 me 5 ko 10. Me tahuri \frac{3}{2} me \frac{2}{5} ki te hautau me te tautūnga 10.
\frac{15+4}{10}
Tā te mea he rite te tauraro o \frac{15}{10} me \frac{4}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{19}{10}
Tāpirihia te 15 ki te 4, ka 19.
