Kua tāruatia ki te papatopenga
20\times 3=d\times 12
Tē taea kia ōrite te tāupe d ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 20d, arā, te tauraro pātahi he tino iti rawa te kitea o d,20.
60=d\times 12
Whakareatia te 20 ki te 3, ka 60.
d\times 12=60
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
d=\frac{60}{12}
Whakawehea ngā taha e rua ki te 12.
d=5
Whakawehea te 60 ki te 12, kia riro ko 5.
