Kua tāruatia ki te papatopenga
-\frac{480+7}{10}-91.8
Whakareatia te 48 ki te 10, ka 480.
-\frac{487}{10}-91.8
Tāpirihia te 480 ki te 7, ka 487.
-\frac{487}{10}-\frac{459}{5}
Me tahuri ki tau ā-ira 91.8 ki te hautau \frac{918}{10}. Whakahekea te hautanga \frac{918}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
-\frac{487}{10}-\frac{918}{10}
Ko te maha noa iti rawa atu o 10 me 5 ko 10. Me tahuri -\frac{487}{10} me \frac{459}{5} ki te hautau me te tautūnga 10.
\frac{-487-918}{10}
Tā te mea he rite te tauraro o -\frac{487}{10} me \frac{918}{10}, me tango rāua mā te tango i ō raua taurunga.
\frac{-1405}{10}
Tangohia te 918 i te -487, ka -1405.
-\frac{281}{2}
Whakahekea te hautanga \frac{-1405}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
