Whakaoti mō d
d = \frac{45}{2} = 22\frac{1}{2} = 22.5
Tohaina
Kua tāruatia ki te papatopenga
d+5d=135
Me tāpiri te 5d ki ngā taha e rua.
6d=135
Pahekotia te d me 5d, ka 6d.
d=\frac{135}{6}
Whakawehea ngā taha e rua ki te 6.
d=\frac{45}{2}
Whakahekea te hautanga \frac{135}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
