Tohaina
Kua tāruatia ki te papatopenga
p=\frac{1}{6}+\frac{1}{4}
Me tāpiri te \frac{1}{4} ki ngā taha e rua.
p=\frac{2}{12}+\frac{3}{12}
Ko te maha noa iti rawa atu o 6 me 4 ko 12. Me tahuri \frac{1}{6} me \frac{1}{4} ki te hautau me te tautūnga 12.
p=\frac{2+3}{12}
Tā te mea he rite te tauraro o \frac{2}{12} me \frac{3}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
p=\frac{5}{12}
Tāpirihia te 2 ki te 3, ka 5.
