Whakaoti i te 10divx=2.5div0.8

$$10 \div x=2.5 \div 0.8$$

Whakaoti mō x

$$x=3.2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$10=x\times \frac{2.5}{0.8}$$

Whakarohaina te \frac{2.5}{0.8} mā te whakarea i te taurunga me te tauraro ki te 10.

$$10=x\times \frac{25}{8}$$

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

$$x\times \frac{25}{8}=10$$

Me whakarea ngā taha e rua ki te \frac{8}{25}, te tau utu o \frac{25}{8}.

$$x=10\times \frac{8}{25}$$

Tuhia te 10\times \frac{8}{25} hei hautanga kotahi.

$$x=\frac{10\times 8}{25}$$

Whakareatia te 10 ki te 8, ka 80.

$$x=\frac{80}{25}$$

Whakahekea te hautanga \frac{80}{25} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=\frac{16}{5}$$
