Kua tāruatia ki te papatopenga
\frac{2}{3}n=16-6
Tangohia te 6 mai i ngā taha e rua.
\frac{2}{3}n=10
Tangohia te 6 i te 16, ka 10.
n=10\times \frac{3}{2}
Me whakarea ngā taha e rua ki te \frac{3}{2}, te tau utu o \frac{2}{3}.
n=\frac{10\times 3}{2}
Tuhia te 10\times \frac{3}{2} hei hautanga kotahi.
n=\frac{30}{2}
Whakareatia te 10 ki te 3, ka 30.
n=15
Whakawehea te 30 ki te 2, kia riro ko 15.
