Whakaoti i te x/y*100=4y/y*100

$$\frac{ x }{ y } \times 100= \frac{ 4y }{ y } \times 100$$

Whakaoti mō x

$$x=4y$$

$$y\neq 0$$

Ngā Upane Otinga

Me whakakore te 100 ki ngā taha e rua.

$$\frac{x}{y}=\frac{4y}{y}$$

Whakareatia ngā taha e rua o te whārite ki te y.

$$x=4y$$

Whakaoti mō y

$$y=\frac{x}{4}$$

$$x\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakakore te 100 ki ngā taha e rua.

$$\frac{x}{y}=\frac{4y}{y}$$

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

$$x=4y$$

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

$$4y=x$$

Whakawehea ngā taha e rua ki te 4.

$$\frac{4y}{4}=\frac{x}{4}$$

Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.

$$y=\frac{x}{4}$$

Tē taea kia ōrite te tāupe y ki 0.

$$y=\frac{x}{4}\text{, }y\neq 0$$
