Kua tāruatia ki te papatopenga
1.4x\times 0.8=2240
Tāpirihia te 1 ki te 0.4, ka 1.4.
1.12x=2240
Whakareatia te 1.4 ki te 0.8, ka 1.12.
x=\frac{2240}{1.12}
Whakawehea ngā taha e rua ki te 1.12.
x=\frac{224000}{112}
Whakarohaina te \frac{2240}{1.12} mā te whakarea i te taurunga me te tauraro ki te 100.
x=2000
Whakawehea te 224000 ki te 112, kia riro ko 2000.
