Kua tāruatia ki te papatopenga
2\times 18\times \frac{x}{360}=12
Me whakakore te \pi ki ngā taha e rua.
2\times 18x=4320
Whakareatia ngā taha e rua o te whārite ki te 360.
36x=4320
Whakareatia te 2 ki te 18, ka 36.
x=\frac{4320}{36}
Whakawehea ngā taha e rua ki te 36.
x=120
Whakawehea te 4320 ki te 36, kia riro ko 120.
