Kua tāruatia ki te papatopenga
y=\frac{3}{4}+\frac{2}{5}
Me tāpiri te \frac{2}{5} ki ngā taha e rua.
y=\frac{15}{20}+\frac{8}{20}
Ko te maha noa iti rawa atu o 4 me 5 ko 20. Me tahuri \frac{3}{4} me \frac{2}{5} ki te hautau me te tautūnga 20.
y=\frac{15+8}{20}
Tā te mea he rite te tauraro o \frac{15}{20} me \frac{8}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
y=\frac{23}{20}
Tāpirihia te 15 ki te 8, ka 23.
