Whakaoti i te 1/2*82*1=2*10*x

$$\frac { 1 } { 2 } \times 82 \times 1 = 2 \times 10 \times x$$

Whakaoti mō x

$$x = \frac{41}{20} = 2\frac{1}{20} = 2.05$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te \frac{1}{2} ki te 82, ka \frac{82}{2}.

$$\frac{82}{2}\times 1=2\times 10x$$

Whakawehea te 82 ki te 2, kia riro ko 41.

$$41\times 1=2\times 10x$$

Whakareatia te 41 ki te 1, ka 41.

$$41=2\times 10x$$

Whakareatia te 2 ki te 10, ka 20.

$$41=20x$$

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

$$20x=41$$

Whakawehea ngā taha e rua ki te 20.

$$x=\frac{41}{20}$$
