Whakaoti mō s
s=10
Tohaina
Kua tāruatia ki te papatopenga
s\times 15=25\times 6
Tē taea kia ōrite te tāupe s ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 25s, arā, te tauraro pātahi he tino iti rawa te kitea o 25,s.
s\times 15=150
Whakareatia te 25 ki te 6, ka 150.
s=\frac{150}{15}
Whakawehea ngā taha e rua ki te 15.
s=10
Whakawehea te 150 ki te 15, kia riro ko 10.
