Kua tāruatia ki te papatopenga
cr=20520-270
Whakareatia ngā taha e rua o te whārite ki te 2.
cr=20250
Tangohia te 270 i te 20520, ka 20250.
rc=20250
He hanga arowhānui tō te whārite.
\frac{rc}{r}=\frac{20250}{r}
Whakawehea ngā taha e rua ki te r.
c=\frac{20250}{r}
Mā te whakawehe ki te r ka wetekia te whakareanga ki te r.
cr=20520-270
Whakareatia ngā taha e rua o te whārite ki te 2.
cr=20250
Tangohia te 270 i te 20520, ka 20250.
\frac{cr}{c}=\frac{20250}{c}
Whakawehea ngā taha e rua ki te c.
r=\frac{20250}{c}
Mā te whakawehe ki te c ka wetekia te whakareanga ki te c.
