Kua tāruatia ki te papatopenga
-\frac{1}{4}\times \frac{4}{7}=x
Me whakarea ngā taha e rua ki te \frac{4}{7}, te tau utu o \frac{7}{4}.
\frac{-4}{4\times 7}=x
Me whakarea te -\frac{1}{4} ki te \frac{4}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{-1}{7}=x
Me whakakore tahi te 4 i te taurunga me te tauraro.
-\frac{1}{7}=x
Ka taea te hautanga \frac{-1}{7} te tuhi anō ko -\frac{1}{7} mā te tango i te tohu tōraro.
x=-\frac{1}{7}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
