Kua tāruatia ki te papatopenga
2.25c\leq 20-10.25
Tangohia te 10.25 mai i ngā taha e rua.
2.25c\leq 9.75
Tangohia te 10.25 i te 20, ka 9.75.
c\leq \frac{9.75}{2.25}
Whakawehea ngā taha e rua ki te 2.25. I te mea he tōrunga te 2.25, kāore e huri te ahunga koreōrite.
c\leq \frac{975}{225}
Whakarohaina te \frac{9.75}{2.25} mā te whakarea i te taurunga me te tauraro ki te 100.
c\leq \frac{13}{3}
Whakahekea te hautanga \frac{975}{225} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 75.
