Whakaoti mō d
d=\frac{7}{10}=0.7
Tohaina
Kua tāruatia ki te papatopenga
d=\frac{3}{10}+\frac{2}{5}
Me tāpiri te \frac{2}{5} ki ngā taha e rua.
d=\frac{3}{10}+\frac{4}{10}
Ko te maha noa iti rawa atu o 10 me 5 ko 10. Me tahuri \frac{3}{10} me \frac{2}{5} ki te hautau me te tautūnga 10.
d=\frac{3+4}{10}
Tā te mea he rite te tauraro o \frac{3}{10} me \frac{4}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
d=\frac{7}{10}
Tāpirihia te 3 ki te 4, ka 7.
