\frac{-8\times 4}{5\times 5}
Me whakarea te -\frac{8}{5} ki te \frac{4}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{-32}{25}
Mahia ngā whakarea i roto i te hautanga \frac{-8\times 4}{5\times 5}.
-\frac{32}{25}
Ka taea te hautanga \frac{-32}{25} te tuhi anō ko -\frac{32}{25} mā te tango i te tohu tōraro.
