Kua tāruatia ki te papatopenga
\frac{28}{4}\geq x
Whakawehea ngā taha e rua ki te 4. I te mea he tōrunga te 4, kāore e huri te ahunga koreōrite.
7\geq x
Whakawehea te 28 ki te 4, kia riro ko 7.
x\leq 7
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
