Whakaoti mō r
r = -\frac{35}{4} = -8\frac{3}{4} = -8.75
Tohaina
Kua tāruatia ki te papatopenga
r=-7\times \frac{5}{4}
Me whakarea ngā taha e rua ki te \frac{5}{4}, te tau utu o \frac{4}{5}.
r=\frac{-7\times 5}{4}
Tuhia te -7\times \frac{5}{4} hei hautanga kotahi.
r=\frac{-35}{4}
Whakareatia te -7 ki te 5, ka -35.
r=-\frac{35}{4}
Ka taea te hautanga \frac{-35}{4} te tuhi anō ko -\frac{35}{4} mā te tango i te tohu tōraro.
