Ngā Upane Otinga

Whakareatia te 9 ki te 8, ka 72.

$$1-\frac{72\times 7\times 4}{10^{4}}$$

Whakareatia te 72 ki te 7, ka 504.

$$1-\frac{504\times 4}{10^{4}}$$

Whakareatia te 504 ki te 4, ka 2016.

$$1-\frac{2016}{10^{4}}$$

Tātaihia te 10 mā te pū o 4, kia riro ko 10000.

$$1-\frac{2016}{10000}$$

Whakahekea te hautanga \frac{2016}{10000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.

$$1-\frac{126}{625}$$

Me tahuri te 1 ki te hautau \frac{625}{625}.

$$\frac{625}{625}-\frac{126}{625}$$

Tā te mea he rite te tauraro o \frac{625}{625} me \frac{126}{625}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{625-126}{625}$$

Tangohia te 126 i te 625, ka 499.

$$\frac{499}{625}$$

Tauwehe

$$\frac{499}{5 ^ {4}} = 0.7984$$
