Tohaina
Kua tāruatia ki te papatopenga
\frac{-8\times 4}{7\times 2}
Whakawehe -\frac{8}{7} ki te \frac{2}{4} mā te whakarea -\frac{8}{7} ki te tau huripoki o \frac{2}{4}.
\frac{-4\times 4}{7}
Me whakakore tahi te 2 i te taurunga me te tauraro.
\frac{-16}{7}
Whakareatia te -4 ki te 4, ka -16.
-\frac{16}{7}
Ka taea te hautanga \frac{-16}{7} te tuhi anō ko -\frac{16}{7} mā te tango i te tohu tōraro.
