Kua tāruatia ki te papatopenga
y\times 112=98\times 5.6
Tē taea kia ōrite te tāupe y ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 98y, arā, te tauraro pātahi he tino iti rawa te kitea o 98,y.
y\times 112=548.8
Whakareatia te 98 ki te 5.6, ka 548.8.
y=\frac{548.8}{112}
Whakawehea ngā taha e rua ki te 112.
y=\frac{5488}{1120}
Whakarohaina te \frac{548.8}{112} mā te whakarea i te taurunga me te tauraro ki te 10.
y=\frac{49}{10}
Whakahekea te hautanga \frac{5488}{1120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 112.
