Whakaoti i te 3xdiv10=9div20

$$3x \div 10=9 \div 20$$

Whakaoti mō x

$$x = \frac{3}{2} = 1\frac{1}{2} = 1.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te 10.

$$3x=\frac{9}{20}\times 10$$

Tuhia te \frac{9}{20}\times 10 hei hautanga kotahi.

$$3x=\frac{9\times 10}{20}$$

Whakareatia te 9 ki te 10, ka 90.

$$3x=\frac{90}{20}$$

Whakahekea te hautanga \frac{90}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$3x=\frac{9}{2}$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{\frac{9}{2}}{3}$$

Tuhia te \frac{\frac{9}{2}}{3} hei hautanga kotahi.

$$x=\frac{9}{2\times 3}$$

Whakareatia te 2 ki te 3, ka 6.

$$x=\frac{9}{6}$$

Whakahekea te hautanga \frac{9}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{3}{2}$$
