1.8x>245-200
Tangohia te 200 mai i ngā taha e rua.
1.8x>45
Tangohia te 200 i te 245, ka 45.
x>\frac{45}{1.8}
Whakawehea ngā taha e rua ki te 1.8. I te mea he tōrunga te 1.8, kāore e huri te ahunga koreōrite.
x>\frac{450}{18}
Whakarohaina te \frac{45}{1.8} mā te whakarea i te taurunga me te tauraro ki te 10.
x>25
Whakawehea te 450 ki te 18, kia riro ko 25.
