Kua tāruatia ki te papatopenga
\frac{3}{2}v=-\frac{1}{2}+\frac{4}{3}
Me tāpiri te \frac{4}{3} ki ngā taha e rua.
\frac{3}{2}v=-\frac{3}{6}+\frac{8}{6}
Ko te maha noa iti rawa atu o 2 me 3 ko 6. Me tahuri -\frac{1}{2} me \frac{4}{3} ki te hautau me te tautūnga 6.
\frac{3}{2}v=\frac{-3+8}{6}
Tā te mea he rite te tauraro o -\frac{3}{6} me \frac{8}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{3}{2}v=\frac{5}{6}
Tāpirihia te -3 ki te 8, ka 5.
v=\frac{5}{6}\times \frac{2}{3}
Me whakarea ngā taha e rua ki te \frac{2}{3}, te tau utu o \frac{3}{2}.
v=\frac{5\times 2}{6\times 3}
Me whakarea te \frac{5}{6} ki te \frac{2}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
v=\frac{10}{18}
Mahia ngā whakarea i roto i te hautanga \frac{5\times 2}{6\times 3}.
v=\frac{5}{9}
Whakahekea te hautanga \frac{10}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
