Ngā Upane mō te Whakaoti Whārite Rārangi

Whakarohaina te \frac{3.6}{5.8} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{k}{4.9}=\frac{36}{58}$$

Whakahekea te hautanga \frac{36}{58} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{k}{4.9}=\frac{18}{29}$$

Me whakarea ngā taha e rua ki te 4.9.

$$k=\frac{18}{29}\times 4.9$$

Me tahuri ki tau ā-ira 4.9 ki te hautau \frac{49}{10}.

$$k=\frac{18}{29}\times \frac{49}{10}$$

Me whakarea te \frac{18}{29} ki te \frac{49}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$k=\frac{18\times 49}{29\times 10}$$

Mahia ngā whakarea i roto i te hautanga \frac{18\times 49}{29\times 10}.

$$k=\frac{882}{290}$$

Whakahekea te hautanga \frac{882}{290} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$k=\frac{441}{145}$$
