Ngā Upane Otinga

Tuhia te \frac{8}{243}\times 5 hei hautanga kotahi.

$$\frac{8\times 5}{243}+\frac{4}{243}\times 5$$

Whakareatia te 8 ki te 5, ka 40.

$$\frac{40}{243}+\frac{4}{243}\times 5$$

Tuhia te \frac{4}{243}\times 5 hei hautanga kotahi.

$$\frac{40}{243}+\frac{4\times 5}{243}$$

Whakareatia te 4 ki te 5, ka 20.

$$\frac{40}{243}+\frac{20}{243}$$

Tā te mea he rite te tauraro o \frac{40}{243} me \frac{20}{243}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{40+20}{243}$$

Tāpirihia te 40 ki te 20, ka 60.

$$\frac{60}{243}$$

Whakahekea te hautanga \frac{60}{243} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{20}{81}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 5}{3 ^ {4}} = 0.24691358024691357$$
