Whakaoti i te 15*1.8*x*1/3=15.3

$$15 \times 1.8 \times x \times \frac { 1 } { 3 } = 15.3$$

Whakaoti mō x

$$x=1.7$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 15 ki te 1.8, ka 27.

$$27x\times \frac{1}{3}=15.3$$

Whakareatia te 27 ki te \frac{1}{3}, ka \frac{27}{3}.

$$\frac{27}{3}x=15.3$$

Whakawehea te 27 ki te 3, kia riro ko 9.

$$9x=15.3$$

Whakawehea ngā taha e rua ki te 9.

$$x=\frac{15.3}{9}$$

Whakarohaina te \frac{15.3}{9} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{153}{90}$$

Whakahekea te hautanga \frac{153}{90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

$$x=\frac{17}{10}$$
