Ngā Upane Otinga

Tāpirihia te 3 ki te 1.2, ka 4.2.

$$1-0.171\left(1-\frac{3}{4.2}\right)$$

Whakarohaina te \frac{3}{4.2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$1-0.171\left(1-\frac{30}{42}\right)$$

Whakahekea te hautanga \frac{30}{42} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$1-0.171\left(1-\frac{5}{7}\right)$$

Me tahuri te 1 ki te hautau \frac{7}{7}.

$$1-0.171\left(\frac{7}{7}-\frac{5}{7}\right)$$

Tā te mea he rite te tauraro o \frac{7}{7} me \frac{5}{7}, me tango rāua mā te tango i ō raua taurunga.

$$1-0.171\times \frac{7-5}{7}$$

Tangohia te 5 i te 7, ka 2.

$$1-0.171\times \frac{2}{7}$$

Me tahuri ki tau ā-ira 0.171 ki te hautau \frac{171}{1000}.

$$1-\frac{171}{1000}\times \frac{2}{7}$$

Me whakarea te \frac{171}{1000} ki te \frac{2}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$1-\frac{171\times 2}{1000\times 7}$$

Mahia ngā whakarea i roto i te hautanga \frac{171\times 2}{1000\times 7}.

$$1-\frac{342}{7000}$$

Whakahekea te hautanga \frac{342}{7000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$1-\frac{171}{3500}$$

Me tahuri te 1 ki te hautau \frac{3500}{3500}.

$$\frac{3500}{3500}-\frac{171}{3500}$$

Tā te mea he rite te tauraro o \frac{3500}{3500} me \frac{171}{3500}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3500-171}{3500}$$

Tangohia te 171 i te 3500, ka 3329.

$$\frac{3329}{3500}$$

Tauwehe

$$\frac{3329}{7 \cdot 2 ^ {2} \cdot 5 ^ {3}} = 0.9511428571428572$$
