Kua tāruatia ki te papatopenga
1=x\left(\frac{1}{2}+\frac{8}{2}\right)
Me tahuri te 4 ki te hautau \frac{8}{2}.
1=x\times \frac{1+8}{2}
Tā te mea he rite te tauraro o \frac{1}{2} me \frac{8}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
1=x\times \frac{9}{2}
Tāpirihia te 1 ki te 8, ka 9.
x\times \frac{9}{2}=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=1\times \frac{2}{9}
Me whakarea ngā taha e rua ki te \frac{2}{9}, te tau utu o \frac{9}{2}.
x=\frac{2}{9}
Whakareatia te 1 ki te \frac{2}{9}, ka \frac{2}{9}.
