Whakaoti mō j
j = -\frac{63}{2} = -31\frac{1}{2} = -31.5
Tohaina
Kua tāruatia ki te papatopenga
j=-21\times \frac{3}{2}
Me whakarea ngā taha e rua ki te \frac{3}{2}, te tau utu o \frac{2}{3}.
j=\frac{-21\times 3}{2}
Tuhia te -21\times \frac{3}{2} hei hautanga kotahi.
j=\frac{-63}{2}
Whakareatia te -21 ki te 3, ka -63.
j=-\frac{63}{2}
Ka taea te hautanga \frac{-63}{2} te tuhi anō ko -\frac{63}{2} mā te tango i te tohu tōraro.
