Ngā Upane Otinga

Whakareatia te 20 ki te 85, ka 1700.

$$\left(15-\frac{\frac{1700}{285}\times 15}{20}\right)\times 6$$

Whakahekea te hautanga \frac{1700}{285} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\left(15-\frac{\frac{340}{57}\times 15}{20}\right)\times 6$$

Tuhia te \frac{340}{57}\times 15 hei hautanga kotahi.

$$\left(15-\frac{\frac{340\times 15}{57}}{20}\right)\times 6$$

Whakareatia te 340 ki te 15, ka 5100.

$$\left(15-\frac{\frac{5100}{57}}{20}\right)\times 6$$

Whakahekea te hautanga \frac{5100}{57} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\left(15-\frac{\frac{1700}{19}}{20}\right)\times 6$$

Tuhia te \frac{\frac{1700}{19}}{20} hei hautanga kotahi.

$$\left(15-\frac{1700}{19\times 20}\right)\times 6$$

Whakareatia te 19 ki te 20, ka 380.

$$\left(15-\frac{1700}{380}\right)\times 6$$

Whakahekea te hautanga \frac{1700}{380} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$\left(15-\frac{85}{19}\right)\times 6$$

Me tahuri te 15 ki te hautau \frac{285}{19}.

$$\left(\frac{285}{19}-\frac{85}{19}\right)\times 6$$

Tā te mea he rite te tauraro o \frac{285}{19} me \frac{85}{19}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{285-85}{19}\times 6$$

Tangohia te 85 i te 285, ka 200.

$$\frac{200}{19}\times 6$$

Tuhia te \frac{200}{19}\times 6 hei hautanga kotahi.

$$\frac{200\times 6}{19}$$

Whakareatia te 200 ki te 6, ka 1200.

$$\frac{1200}{19}$$

Tauwehe

$$\frac{2 ^ {4} \cdot 3 \cdot 5 ^ {2}}{19} = 63\frac{3}{19} = 63.1578947368421$$
