Kua tāruatia ki te papatopenga
6\times \frac{5}{2}=n-1
Me whakarea ngā taha e rua ki te \frac{5}{2}, te tau utu o \frac{2}{5}.
\frac{6\times 5}{2}=n-1
Tuhia te 6\times \frac{5}{2} hei hautanga kotahi.
\frac{30}{2}=n-1
Whakareatia te 6 ki te 5, ka 30.
15=n-1
Whakawehea te 30 ki te 2, kia riro ko 15.
n-1=15
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
n=15+1
Me tāpiri te 1 ki ngā taha e rua.
n=16
Tāpirihia te 15 ki te 1, ka 16.
