Kua tāruatia ki te papatopenga
4\times \frac{5}{6}=5x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 4x, arā, te tauraro pātahi he tino iti rawa te kitea o x,4.
\frac{4\times 5}{6}=5x
Tuhia te 4\times \frac{5}{6} hei hautanga kotahi.
\frac{20}{6}=5x
Whakareatia te 4 ki te 5, ka 20.
\frac{10}{3}=5x
Whakahekea te hautanga \frac{20}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
5x=\frac{10}{3}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{\frac{10}{3}}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{10}{3\times 5}
Tuhia te \frac{\frac{10}{3}}{5} hei hautanga kotahi.
x=\frac{10}{15}
Whakareatia te 3 ki te 5, ka 15.
x=\frac{2}{3}
Whakahekea te hautanga \frac{10}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
