Ngā Upane Otinga

Whakareatia te 9 ki te 800, ka 7200.

$$7200\times 0.7\times 0.095\times \frac{7}{12}$$

Whakareatia te 7200 ki te 0.7, ka 5040.

$$5040\times 0.095\times \frac{7}{12}$$

Whakareatia te 5040 ki te 0.095, ka 478.8.

$$478.8\times \frac{7}{12}$$

Me tahuri ki tau ā-ira 478.8 ki te hautau \frac{4788}{10}. Whakahekea te hautanga \frac{4788}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{2394}{5}\times \frac{7}{12}$$

Me whakarea te \frac{2394}{5} ki te \frac{7}{12} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{2394\times 7}{5\times 12}$$

Mahia ngā whakarea i roto i te hautanga \frac{2394\times 7}{5\times 12}.

$$\frac{16758}{60}$$

Whakahekea te hautanga \frac{16758}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$\frac{2793}{10}$$

Tauwehe

$$\frac{3 \cdot 19 \cdot 7 ^ {2}}{2 \cdot 5} = 279\frac{3}{10} = 279.3$$
