Tohaina
Kua tāruatia ki te papatopenga
10000+250p+150p=50000
Me tāpiri te 150p ki ngā taha e rua.
10000+400p=50000
Pahekotia te 250p me 150p, ka 400p.
400p=50000-10000
Tangohia te 10000 mai i ngā taha e rua.
400p=40000
Tangohia te 10000 i te 50000, ka 40000.
p=\frac{40000}{400}
Whakawehea ngā taha e rua ki te 400.
p=100
Whakawehea te 40000 ki te 400, kia riro ko 100.
