Tohaina
Kua tāruatia ki te papatopenga
\frac{-\frac{21}{21}+\frac{22}{21}}{\frac{2}{54}}
Me tahuri te -1 ki te hautau -\frac{21}{21}.
\frac{\frac{-21+22}{21}}{\frac{2}{54}}
Tā te mea he rite te tauraro o -\frac{21}{21} me \frac{22}{21}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{\frac{1}{21}}{\frac{2}{54}}
Tāpirihia te -21 ki te 22, ka 1.
\frac{\frac{1}{21}}{\frac{1}{27}}
Whakahekea te hautanga \frac{2}{54} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{1}{21}\times 27
Whakawehe \frac{1}{21} ki te \frac{1}{27} mā te whakarea \frac{1}{21} ki te tau huripoki o \frac{1}{27}.
\frac{27}{21}
Whakareatia te \frac{1}{21} ki te 27, ka \frac{27}{21}.
\frac{9}{7}
Whakahekea te hautanga \frac{27}{21} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
