Whakaoti i te 21/3m=42/3

$$2 \frac { 1 } { 3 } m = 4 \frac { 2 } { 3 }$$

Whakaoti mō m

$$m=2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 3.

$$\left(2\times 3+1\right)m=4\times 3+2$$

Whakareatia te 2 ki te 3, ka 6.

$$\left(6+1\right)m=4\times 3+2$$

Tāpirihia te 6 ki te 1, ka 7.

$$7m=4\times 3+2$$

Whakareatia te 4 ki te 3, ka 12.

$$7m=12+2$$

Tāpirihia te 12 ki te 2, ka 14.

$$7m=14$$

Whakawehea ngā taha e rua ki te 7.

$$m=\frac{14}{7}$$

Whakawehea te 14 ki te 7, kia riro ko 2.

$$m=2$$
