Whakaoti i te x/4.9=5.0/5.8

$$\frac { x } { 4.9 } = \frac { 5.0 } { 5.8 }$$

Whakaoti mō x

$$x = \frac{245}{58} = 4\frac{13}{58} \approx 4.224137931$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakarohaina te \frac{5}{5.8} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{x}{4.9}=\frac{50}{58}$$

Whakahekea te hautanga \frac{50}{58} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{x}{4.9}=\frac{25}{29}$$

Me whakarea ngā taha e rua ki te 4.9.

$$x=\frac{25}{29}\times 4.9$$

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

$$x=\frac{25}{29}\times \frac{49}{10}$$

Me whakarea te \frac{25}{29} ki te \frac{49}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{25\times 49}{29\times 10}$$

Mahia ngā whakarea i roto i te hautanga \frac{25\times 49}{29\times 10}.

$$x=\frac{1225}{290}$$

Whakahekea te hautanga \frac{1225}{290} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=\frac{245}{58}$$
