Kua tāruatia ki te papatopenga
4.4=x\times \frac{2.9}{3.9}
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.
4.4=x\times \frac{29}{39}
Whakarohaina te \frac{2.9}{3.9} mā te whakarea i te taurunga me te tauraro ki te 10.
x\times \frac{29}{39}=4.4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=4.4\times \frac{39}{29}
Me whakarea ngā taha e rua ki te \frac{39}{29}, te tau utu o \frac{29}{39}.
x=\frac{22}{5}\times \frac{39}{29}
Me tahuri ki tau ā-ira 4.4 ki te hautau \frac{44}{10}. Whakahekea te hautanga \frac{44}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x=\frac{22\times 39}{5\times 29}
Me whakarea te \frac{22}{5} ki te \frac{39}{29} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{858}{145}
Mahia ngā whakarea i roto i te hautanga \frac{22\times 39}{5\times 29}.
