Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea te 13x ki te 1.2, kia riro ko \frac{65}{6}x.

$$\frac{65}{6}x=\frac{3}{\frac{50}{100}}$$

Whakawehe 3 ki te \frac{50}{100} mā te whakarea 3 ki te tau huripoki o \frac{50}{100}.

$$\frac{65}{6}x=\frac{3\times 100}{50}$$

Whakareatia te 3 ki te 100, ka 300.

$$\frac{65}{6}x=\frac{300}{50}$$

Whakawehea te 300 ki te 50, kia riro ko 6.

$$\frac{65}{6}x=6$$

Whakawehea ngā taha e rua ki te \frac{65}{6}.

$$x=\frac{6}{\frac{65}{6}}$$
