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