Kua tāruatia ki te papatopenga
\frac{-7\times 4}{12y^{2}}+\frac{5\times 3y}{12y^{2}}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 3y^{2} me 4y ko 12y^{2}. Whakareatia \frac{-7}{3y^{2}} ki te \frac{4}{4}. Whakareatia \frac{5}{4y} ki te \frac{3y}{3y}.
\frac{-7\times 4+5\times 3y}{12y^{2}}
Tā te mea he rite te tauraro o \frac{-7\times 4}{12y^{2}} me \frac{5\times 3y}{12y^{2}}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{-28+15y}{12y^{2}}
Mahia ngā whakarea i roto o -7\times 4+5\times 3y.
