5 raruraru e ōrite ana ki:
\frac { 1800 } { x } - \frac { 1800 } { 25 x } = 16
Tohaina
Kua tāruatia ki te papatopenga
25\times 1800-1800=400x
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 25x, arā, te tauraro pātahi he tino iti rawa te kitea o x,25x.
45000-1800=400x
Whakareatia te 25 ki te 1800, ka 45000.
43200=400x
Tangohia te 1800 i te 45000, ka 43200.
400x=43200
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{43200}{400}
Whakawehea ngā taha e rua ki te 400.
x=108
Whakawehea te 43200 ki te 400, kia riro ko 108.
