Whakaoti i te (2/3-19/6+05)

$$( \frac { 2 } { 3 } - \frac { 19 } { 6 } + 05 )$$

Aromātai

$$-\frac{5}{2}=-2.5$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 6 ko 6. Me tahuri \frac{2}{3} me \frac{19}{6} ki te hautau me te tautūnga 6.

$$\frac{4}{6}-\frac{19}{6}+0\times 5$$

Tā te mea he rite te tauraro o \frac{4}{6} me \frac{19}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{4-19}{6}+0\times 5$$

Tangohia te 19 i te 4, ka -15.

$$\frac{-15}{6}+0\times 5$$

Whakahekea te hautanga \frac{-15}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{5}{2}+0\times 5$$

Whakareatia te 0 ki te 5, ka 0.

$$-\frac{5}{2}+0$$

Tāpirihia te -\frac{5}{2} ki te 0, ka -\frac{5}{2}.

$$-\frac{5}{2}$$

Tauwehe

$$-\frac{5}{2} = -2\frac{1}{2} = -2.5$$
