Tohaina
Kua tāruatia ki te papatopenga
0.04A=820
Pahekotia te 1.04A me -A, ka 0.04A.
A=\frac{820}{0.04}
Whakawehea ngā taha e rua ki te 0.04.
A=\frac{82000}{4}
Whakarohaina te \frac{820}{0.04} mā te whakarea i te taurunga me te tauraro ki te 100.
A=20500
Whakawehea te 82000 ki te 4, kia riro ko 20500.
