Kua tāruatia ki te papatopenga
-\frac{4}{5}+7.8
Ko te tauaro o -7.8 ko 7.8.
-\frac{4}{5}+\frac{39}{5}
Me tahuri ki tau ā-ira 7.8 ki te hautau \frac{78}{10}. Whakahekea te hautanga \frac{78}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{-4+39}{5}
Tā te mea he rite te tauraro o -\frac{4}{5} me \frac{39}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{35}{5}
Tāpirihia te -4 ki te 39, ka 35.
7
Whakawehea te 35 ki te 5, kia riro ko 7.
