Kua tāruatia ki te papatopenga
99=0.75x
Whakareatia te 45 ki te 2.2, ka 99.
0.75x=99
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{99}{0.75}
Whakawehea ngā taha e rua ki te 0.75.
x=\frac{9900}{75}
Whakarohaina te \frac{99}{0.75} mā te whakarea i te taurunga me te tauraro ki te 100.
x=132
Whakawehea te 9900 ki te 75, kia riro ko 132.
