Tohaina
Kua tāruatia ki te papatopenga
-\frac{1}{8}-\left(-98.5\right)
Ka taea te hautanga \frac{-1}{8} te tuhi anō ko -\frac{1}{8} mā te tango i te tohu tōraro.
-\frac{1}{8}+98.5
Ko te tauaro o -98.5 ko 98.5.
-\frac{1}{8}+\frac{197}{2}
Me tahuri ki tau ā-ira 98.5 ki te hautau \frac{985}{10}. Whakahekea te hautanga \frac{985}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
-\frac{1}{8}+\frac{788}{8}
Ko te maha noa iti rawa atu o 8 me 2 ko 8. Me tahuri -\frac{1}{8} me \frac{197}{2} ki te hautau me te tautūnga 8.
\frac{-1+788}{8}
Tā te mea he rite te tauraro o -\frac{1}{8} me \frac{788}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{787}{8}
Tāpirihia te -1 ki te 788, ka 787.
