Kua tāruatia ki te papatopenga
x\times \frac{84}{8.4}=120
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
x\times \frac{840}{84}=120
Whakarohaina te \frac{84}{8.4} mā te whakarea i te taurunga me te tauraro ki te 10.
x\times 10=120
Whakawehea te 840 ki te 84, kia riro ko 10.
x=\frac{120}{10}
Whakawehea ngā taha e rua ki te 10.
x=12
Whakawehea te 120 ki te 10, kia riro ko 12.
