18+625x<85
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
625x<85-18
Tangohia te 18 mai i ngā taha e rua.
625x<67
Tangohia te 18 i te 85, ka 67.
x<\frac{67}{625}
Whakawehea ngā taha e rua ki te 625. I te mea he tōrunga te 625, kāore e huri te ahunga koreōrite.
