\frac{-\frac{3}{5}}{\frac{7}{7}-\frac{2}{7}}
Me tahuri te 1 ki te hautau \frac{7}{7}.
\frac{-\frac{3}{5}}{\frac{7-2}{7}}
Tā te mea he rite te tauraro o \frac{7}{7} me \frac{2}{7}, me tango rāua mā te tango i ō raua taurunga.
\frac{-\frac{3}{5}}{\frac{5}{7}}
Tangohia te 2 i te 7, ka 5.
-\frac{3}{5}\times \frac{7}{5}
Whakawehe -\frac{3}{5} ki te \frac{5}{7} mā te whakarea -\frac{3}{5} ki te tau huripoki o \frac{5}{7}.
\frac{-3\times 7}{5\times 5}
Me whakarea te -\frac{3}{5} ki te \frac{7}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{-21}{25}
Mahia ngā whakarea i roto i te hautanga \frac{-3\times 7}{5\times 5}.
-\frac{21}{25}
Ka taea te hautanga \frac{-21}{25} te tuhi anō ko -\frac{21}{25} mā te tango i te tohu tōraro.
