Whakaoti i te (-9/4)+1/4-1/2

$$( - \frac { 9 } { 4 } ) + \frac { 1 } { 4 } - \frac { 1 } { 2 }$$

Aromātai

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

Ngā Upane Otinga

Tā te mea he rite te tauraro o -\frac{9}{4} me \frac{1}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-9+1}{4}-\frac{1}{2}$$

Tāpirihia te -9 ki te 1, ka -8.

$$\frac{-8}{4}-\frac{1}{2}$$

Whakawehea te -8 ki te 4, kia riro ko -2.

$$-2-\frac{1}{2}$$

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

$$-\frac{4}{2}-\frac{1}{2}$$

Tā te mea he rite te tauraro o -\frac{4}{2} me \frac{1}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-4-1}{2}$$

Tangohia te 1 i te -4, ka -5.

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

Tauwehe

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