Whakaoti i te -2/3*2+13/2

$$- \frac { 2 } { 3 } \times 2 + \frac { 13 } { 2 }$$

Aromātai

$$\frac{31}{6}\approx 5.166666667$$

Ngā Upane Otinga

Tuhia te -\frac{2}{3}\times 2 hei hautanga kotahi.

$$\frac{-2\times 2}{3}+\frac{13}{2}$$

Whakareatia te -2 ki te 2, ka -4.

$$\frac{-4}{3}+\frac{13}{2}$$

Ka taea te hautanga \frac{-4}{3} te tuhi anō ko -\frac{4}{3} mā te tango i te tohu tōraro.

$$-\frac{4}{3}+\frac{13}{2}$$

Ko te maha noa iti rawa atu o 3 me 2 ko 6. Me tahuri -\frac{4}{3} me \frac{13}{2} ki te hautau me te tautūnga 6.

$$-\frac{8}{6}+\frac{39}{6}$$

Tā te mea he rite te tauraro o -\frac{8}{6} me \frac{39}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-8+39}{6}$$

Tāpirihia te -8 ki te 39, ka 31.

$$\frac{31}{6}$$

Tauwehe

$$\frac{31}{2 \cdot 3} = 5\frac{1}{6} = 5.166666666666667$$
