Ngā Upane Otinga

Whakahekea te hautanga \frac{243}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$243+\frac{81}{5}+\frac{243}{15}\times \frac{2}{3}$$

Me tahuri te 243 ki te hautau \frac{1215}{5}.

$$\frac{1215}{5}+\frac{81}{5}+\frac{243}{15}\times \frac{2}{3}$$

Tā te mea he rite te tauraro o \frac{1215}{5} me \frac{81}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1215+81}{5}+\frac{243}{15}\times \frac{2}{3}$$

Tāpirihia te 1215 ki te 81, ka 1296.

$$\frac{1296}{5}+\frac{243}{15}\times \frac{2}{3}$$

Whakahekea te hautanga \frac{243}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{1296}{5}+\frac{81}{5}\times \frac{2}{3}$$

Me whakarea te \frac{81}{5} ki te \frac{2}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1296}{5}+\frac{81\times 2}{5\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{81\times 2}{5\times 3}.

$$\frac{1296}{5}+\frac{162}{15}$$

Whakahekea te hautanga \frac{162}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{1296}{5}+\frac{54}{5}$$

Tā te mea he rite te tauraro o \frac{1296}{5} me \frac{54}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1296+54}{5}$$

Tāpirihia te 1296 ki te 54, ka 1350.

$$\frac{1350}{5}$$

Whakawehea te 1350 ki te 5, kia riro ko 270.
