Arithmetic
5 raruraru e ōrite ana ki:
( - 3 \frac { 1 } { 9 } ) \times ( - 1 \frac { 5 } { 7 } )
Tohaina
Kua tāruatia ki te papatopenga
\left(-\frac{27+1}{9}\right)\left(-\frac{1\times 7+5}{7}\right)
Whakareatia te 3 ki te 9, ka 27.
-\frac{28}{9}\left(-\frac{7+5}{7}\right)
Tāpirihia te 27 ki te 1, ka 28.
-\frac{28}{9}\left(-\frac{12}{7}\right)
Tāpirihia te 7 ki te 5, ka 12.
\frac{-28\left(-12\right)}{9\times 7}
Me whakarea te -\frac{28}{9} ki te -\frac{12}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{336}{63}
Mahia ngā whakarea i roto i te hautanga \frac{-28\left(-12\right)}{9\times 7}.
\frac{16}{3}
Whakahekea te hautanga \frac{336}{63} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 21.
