Ngā Upane Otinga

Tuhia te \frac{\frac{2.2\times 7-\frac{17}{36}}{65}}{18} hei hautanga kotahi.

$$\frac{2.2\times 7-\frac{17}{36}}{65\times 18}$$

Whakareatia te 2.2 ki te 7, ka 15.4.

$$\frac{15.4-\frac{17}{36}}{65\times 18}$$

Me tahuri ki tau ā-ira 15.4 ki te hautau \frac{154}{10}. Whakahekea te hautanga \frac{154}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{\frac{77}{5}-\frac{17}{36}}{65\times 18}$$

Ko te maha noa iti rawa atu o 5 me 36 ko 180. Me tahuri \frac{77}{5} me \frac{17}{36} ki te hautau me te tautūnga 180.

$$\frac{\frac{2772}{180}-\frac{85}{180}}{65\times 18}$$

Tā te mea he rite te tauraro o \frac{2772}{180} me \frac{85}{180}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{2772-85}{180}}{65\times 18}$$

Tangohia te 85 i te 2772, ka 2687.

$$\frac{\frac{2687}{180}}{65\times 18}$$

Whakareatia te 65 ki te 18, ka 1170.

$$\frac{\frac{2687}{180}}{1170}$$

Tuhia te \frac{\frac{2687}{180}}{1170} hei hautanga kotahi.

$$\frac{2687}{180\times 1170}$$

Whakareatia te 180 ki te 1170, ka 210600.

$$\frac{2687}{210600}$$

Tauwehe

$$\frac{2687}{13 \cdot 2 ^ {3} \cdot 3 ^ {4} \cdot 5 ^ {2}} = 0.012758784425451091$$
