Kua tāruatia ki te papatopenga
3\times \frac{2\times 10+7}{10}=8\times 10+1
Whakareatia ngā taha e rua o te whārite ki te 10.
3\times \frac{20+7}{10}=8\times 10+1
Whakareatia te 2 ki te 10, ka 20.
3\times \frac{27}{10}=8\times 10+1
Tāpirihia te 20 ki te 7, ka 27.
\frac{3\times 27}{10}=8\times 10+1
Tuhia te 3\times \frac{27}{10} hei hautanga kotahi.
\frac{81}{10}=8\times 10+1
Whakareatia te 3 ki te 27, ka 81.
\frac{81}{10}=80+1
Whakareatia te 8 ki te 10, ka 80.
\frac{81}{10}=81
Tāpirihia te 80 ki te 1, ka 81.
\frac{81}{10}=\frac{810}{10}
Me tahuri te 81 ki te hautau \frac{810}{10}.
\text{false}
Whakatauritea te \frac{81}{10} me te \frac{810}{10}.
