Ngā Upane Otinga

Tuhia te 500\times \frac{22}{7} hei hautanga kotahi.

$$\frac{500\times 22}{7}\times 0.42\times 1.2$$

Whakareatia te 500 ki te 22, ka 11000.

$$\frac{11000}{7}\times 0.42\times 1.2$$

Me tahuri ki tau ā-ira 0.42 ki te hautau \frac{42}{100}. Whakahekea te hautanga \frac{42}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{11000}{7}\times \frac{21}{50}\times 1.2$$

Me whakarea te \frac{11000}{7} ki te \frac{21}{50} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{11000\times 21}{7\times 50}\times 1.2$$

Mahia ngā whakarea i roto i te hautanga \frac{11000\times 21}{7\times 50}.

$$\frac{231000}{350}\times 1.2$$

Whakawehea te 231000 ki te 350, kia riro ko 660.

$$660\times 1.2$$

Whakareatia te 660 ki te 1.2, ka 792.
