Tohaina
Kua tāruatia ki te papatopenga
\frac{12}{\frac{7}{7}-\frac{3}{7}}
Me tahuri te 1 ki te hautau \frac{7}{7}.
\frac{12}{\frac{7-3}{7}}
Tā te mea he rite te tauraro o \frac{7}{7} me \frac{3}{7}, me tango rāua mā te tango i ō raua taurunga.
\frac{12}{\frac{4}{7}}
Tangohia te 3 i te 7, ka 4.
12\times \frac{7}{4}
Whakawehe 12 ki te \frac{4}{7} mā te whakarea 12 ki te tau huripoki o \frac{4}{7}.
\frac{12\times 7}{4}
Tuhia te 12\times \frac{7}{4} hei hautanga kotahi.
\frac{84}{4}
Whakareatia te 12 ki te 7, ka 84.
21
Whakawehea te 84 ki te 4, kia riro ko 21.
