Whakaoti i te 450=8*40+x*60

$$450=8 \times 40+x \times 60$$

Whakaoti mō x

$$x = \frac{13}{6} = 2\frac{1}{6} \approx 2.166666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 8 ki te 40, ka 320.

$$450=320+x\times 60$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$320+x\times 60=450$$

Tangohia te 320 mai i ngā taha e rua.

$$x\times 60=450-320$$

Tangohia te 320 i te 450, ka 130.

$$x\times 60=130$$

Whakawehea ngā taha e rua ki te 60.

$$x=\frac{130}{60}$$

Whakahekea te hautanga \frac{130}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$x=\frac{13}{6}$$
