Whakaoti mō v
v = \frac{7}{4} = 1\frac{3}{4} = 1.75
Tohaina
Kua tāruatia ki te papatopenga
20v=7\times 5
Tē taea kia ōrite te tāupe v ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 14v, arā, te tauraro pātahi he tino iti rawa te kitea o 7,2v.
20v=35
Whakareatia te 7 ki te 5, ka 35.
v=\frac{35}{20}
Whakawehea ngā taha e rua ki te 20.
v=\frac{7}{4}
Whakahekea te hautanga \frac{35}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
