Kua tāruatia ki te papatopenga
-2.8\left(-\frac{7+1}{7}\right)
Whakareatia te 1 ki te 7, ka 7.
-2.8\left(-\frac{8}{7}\right)
Tāpirihia te 7 ki te 1, ka 8.
-\frac{14}{5}\left(-\frac{8}{7}\right)
Me tahuri ki tau ā-ira -2.8 ki te hautau -\frac{28}{10}. Whakahekea te hautanga -\frac{28}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{-14\left(-8\right)}{5\times 7}
Me whakarea te -\frac{14}{5} ki te -\frac{8}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{112}{35}
Mahia ngā whakarea i roto i te hautanga \frac{-14\left(-8\right)}{5\times 7}.
\frac{16}{5}
Whakahekea te hautanga \frac{112}{35} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.
