Kua tāruatia ki te papatopenga
\frac{2}{3}a>12-8
Tangohia te 8 mai i ngā taha e rua.
\frac{2}{3}a>4
Tangohia te 8 i te 12, ka 4.
a>4\times \frac{3}{2}
Me whakarea ngā taha e rua ki te \frac{3}{2}, te tau utu o \frac{2}{3}. I te mea he tōrunga te \frac{2}{3}, kāore e huri te ahunga koreōrite.
a>\frac{4\times 3}{2}
Tuhia te 4\times \frac{3}{2} hei hautanga kotahi.
a>\frac{12}{2}
Whakareatia te 4 ki te 3, ka 12.
a>6
Whakawehea te 12 ki te 2, kia riro ko 6.
