Kua tāruatia ki te papatopenga
21=300x
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.
300x=21
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{21}{300}
Whakawehea ngā taha e rua ki te 300.
x=\frac{7}{100}
Whakahekea te hautanga \frac{21}{300} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
