Whakaoti i te 2/3left(y-1right)=1/6

$$\frac{ 2 }{ 3 } \left( y-1 \right) = \frac{ 1 }{ 6 }$$

Whakaoti mō y

$$y = \frac{5}{4} = 1\frac{1}{4} = 1.25$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te \frac{3}{2}, te tau utu o \frac{2}{3}.

$$y-1=\frac{1}{6}\times \frac{3}{2}$$

Me whakarea te \frac{1}{6} ki te \frac{3}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$y-1=\frac{1\times 3}{6\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 3}{6\times 2}.

$$y-1=\frac{3}{12}$$

Whakahekea te hautanga \frac{3}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$y-1=\frac{1}{4}$$

Me tāpiri te 1 ki ngā taha e rua.

$$y=\frac{1}{4}+1$$

Me tahuri te 1 ki te hautau \frac{4}{4}.

$$y=\frac{1}{4}+\frac{4}{4}$$

Tā te mea he rite te tauraro o \frac{1}{4} me \frac{4}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$y=\frac{1+4}{4}$$

Tāpirihia te 1 ki te 4, ka 5.

$$y=\frac{5}{4}$$
