Whakaoti i te 3/9=a-2

$$3 / 9 = a - 2$$

Whakaoti mō a

$$a = \frac{7}{3} = 2\frac{1}{3} \approx 2.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$\frac{1}{3}=a-2$$

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

$$a-2=\frac{1}{3}$$

Me tāpiri te 2 ki ngā taha e rua.

$$a=\frac{1}{3}+2$$

Me tahuri te 2 ki te hautau \frac{6}{3}.

$$a=\frac{1}{3}+\frac{6}{3}$$

Tā te mea he rite te tauraro o \frac{1}{3} me \frac{6}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$a=\frac{1+6}{3}$$

Tāpirihia te 1 ki te 6, ka 7.

$$a=\frac{7}{3}$$
