\frac{4\times 2}{18y}+\frac{7\times 3}{18y}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 9y me 6y ko 18y. Whakareatia \frac{4}{9y} ki te \frac{2}{2}. Whakareatia \frac{7}{6y} ki te \frac{3}{3}.
\frac{4\times 2+7\times 3}{18y}
Tā te mea he rite te tauraro o \frac{4\times 2}{18y} me \frac{7\times 3}{18y}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{8+21}{18y}
Mahia ngā whakarea i roto o 4\times 2+7\times 3.
\frac{29}{18y}
Mahia ngā tātaitai i roto o 8+21.
