Kua tāruatia ki te papatopenga
\frac{6}{7}\times 91=d
Me whakarea ngā taha e rua ki te 91.
\frac{6\times 91}{7}=d
Tuhia te \frac{6}{7}\times 91 hei hautanga kotahi.
\frac{546}{7}=d
Whakareatia te 6 ki te 91, ka 546.
78=d
Whakawehea te 546 ki te 7, kia riro ko 78.
d=78
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
