Whakaoti i te 0.8x=112div12

$$0.8x=112 \div 12$$

Whakaoti mō x

$$x = \frac{35}{3} = 11\frac{2}{3} \approx 11.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{112}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$0.8x=\frac{28}{3}$$

Whakawehea ngā taha e rua ki te 0.8.

$$x=\frac{\frac{28}{3}}{0.8}$$

Tuhia te \frac{\frac{28}{3}}{0.8} hei hautanga kotahi.

$$x=\frac{28}{3\times 0.8}$$

Whakareatia te 3 ki te 0.8, ka 2.4.

$$x=\frac{28}{2.4}$$

Whakarohaina te \frac{28}{2.4} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{280}{24}$$

Whakahekea te hautanga \frac{280}{24} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$x=\frac{35}{3}$$
