Whakaoti i te 10a=r/d

$$10 a = \frac { r } { d }$$

Whakaoti mō a

$$a=\frac{r}{10d}$$

$$d\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$10ad=r$$

He hanga arowhānui tō te whārite.

$$10da=r$$

Whakawehea ngā taha e rua ki te 10d.

$$\frac{10da}{10d}=\frac{r}{10d}$$

Mā te whakawehe ki te 10d ka wetekia te whakareanga ki te 10d.

$$a=\frac{r}{10d}$$

Whakaoti mō d

$$\left\{\begin{matrix}d=\frac{r}{10a}\text{, }&r\neq 0\text{ and }a\neq 0\\d\neq 0\text{, }&a=0\text{ and }r=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$10ad=r$$

Whakawehea ngā taha e rua ki te 10a.

$$\frac{10ad}{10a}=\frac{r}{10a}$$

Mā te whakawehe ki te 10a ka wetekia te whakareanga ki te 10a.

$$d=\frac{r}{10a}$$

Tē taea kia ōrite te tāupe d ki 0.

$$d=\frac{r}{10a}\text{, }d\neq 0$$
