Ngā Upane Otinga

Whakareatia te 0.75 ki te 0.5, ka 0.375.

$$\frac{3}{0.375+1\times 0.4+1.5\times 0.1}$$

Whakareatia te 1 ki te 0.4, ka 0.4.

$$\frac{3}{0.375+0.4+1.5\times 0.1}$$

Tāpirihia te 0.375 ki te 0.4, ka 0.775.

$$\frac{3}{0.775+1.5\times 0.1}$$

Whakareatia te 1.5 ki te 0.1, ka 0.15.

$$\frac{3}{0.775+0.15}$$

Tāpirihia te 0.775 ki te 0.15, ka 0.925.

$$\frac{3}{0.925}$$

Whakarohaina te \frac{3}{0.925} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$\frac{3000}{925}$$

Whakahekea te hautanga \frac{3000}{925} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{120}{37}$$

Tauwehe

$$\frac{3 \cdot 5 \cdot 2 ^ {3}}{37} = 3\frac{9}{37} = 3.2432432432432434$$
