Tohaina
Kua tāruatia ki te papatopenga
28mk=300m
He hanga arowhānui tō te whārite.
\frac{28mk}{28m}=\frac{300m}{28m}
Whakawehea ngā taha e rua ki te 28m.
k=\frac{300m}{28m}
Mā te whakawehe ki te 28m ka wetekia te whakareanga ki te 28m.
k=\frac{75}{7}
Whakawehe 300m ki te 28m.
28km-300m=0
Tangohia te 300m mai i ngā taha e rua.
\left(28k-300\right)m=0
Pahekotia ngā kīanga tau katoa e whai ana i te m.
m=0
Whakawehe 0 ki te 28k-300.
