Kua tāruatia ki te papatopenga
\frac{25}{4}\left(-\frac{6}{5}\right)
Tātaihia te \frac{5}{2} mā te pū o 2, kia riro ko \frac{25}{4}.
\frac{25\left(-6\right)}{4\times 5}
Me whakarea te \frac{25}{4} ki te -\frac{6}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{-150}{20}
Mahia ngā whakarea i roto i te hautanga \frac{25\left(-6\right)}{4\times 5}.
-\frac{15}{2}
Whakahekea te hautanga \frac{-150}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
