Kua tāruatia ki te papatopenga
-4.8\left(-\frac{7}{12}\right)
Ka taea te hautanga \frac{-7}{12} te tuhi anō ko -\frac{7}{12} mā te tango i te tohu tōraro.
-\frac{24}{5}\left(-\frac{7}{12}\right)
Me tahuri ki tau ā-ira -4.8 ki te hautau -\frac{48}{10}. Whakahekea te hautanga -\frac{48}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{-24\left(-7\right)}{5\times 12}
Me whakarea te -\frac{24}{5} ki te -\frac{7}{12} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{168}{60}
Mahia ngā whakarea i roto i te hautanga \frac{-24\left(-7\right)}{5\times 12}.
\frac{14}{5}
Whakahekea te hautanga \frac{168}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
