Whakaoti i te 1/2-4+1/3=?

$$\frac { 1 } { 2 } - 4 + \frac { 1 } { 3 } = ?$$

Aromātai

$$-\frac{19}{6}\approx -3.166666667$$

Ngā Upane Otinga

Me tahuri te 4 ki te hautau \frac{8}{2}.

$$\frac{1}{2}-\frac{8}{2}+\frac{1}{3}$$

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{8}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1-8}{2}+\frac{1}{3}$$

Tangohia te 8 i te 1, ka -7.

$$-\frac{7}{2}+\frac{1}{3}$$

Ko te maha noa iti rawa atu o 2 me 3 ko 6. Me tahuri -\frac{7}{2} me \frac{1}{3} ki te hautau me te tautūnga 6.

$$-\frac{21}{6}+\frac{2}{6}$$

Tā te mea he rite te tauraro o -\frac{21}{6} me \frac{2}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-21+2}{6}$$

Tāpirihia te -21 ki te 2, ka -19.

$$-\frac{19}{6}$$

Tauwehe

$$-\frac{19}{6} = -3\frac{1}{6} = -3.1666666666666665$$
