Tohaina
Kua tāruatia ki te papatopenga
50\times 2=50R\times \frac{1}{25}+50R\left(-\frac{1}{50}\right)
Tē taea kia ōrite te tāupe R ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 50R, arā, te tauraro pātahi he tino iti rawa te kitea o R,25,50.
100=50R\times \frac{1}{25}+50R\left(-\frac{1}{50}\right)
Whakareatia te 50 ki te 2, ka 100.
100=\frac{50}{25}R+50R\left(-\frac{1}{50}\right)
Whakareatia te 50 ki te \frac{1}{25}, ka \frac{50}{25}.
100=2R+50R\left(-\frac{1}{50}\right)
Whakawehea te 50 ki te 25, kia riro ko 2.
100=2R-R
Me whakakore te 50 me te 50.
100=R
Pahekotia te 2R me -R, ka R.
R=100
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
