Whakaoti i te 5/12-(-1/3)+(-1/4)

$$\frac { 5 } { 12 } - ( - \frac { 1 } { 3 } ) + ( - \frac { 1 } { 4 } )$$

Aromātai

$$\frac{1}{2}=0.5$$

Ngā Upane Otinga

Ko te tauaro o -\frac{1}{3} ko \frac{1}{3}.

$$\frac{5}{12}+\frac{1}{3}-\frac{1}{4}$$

Ko te maha noa iti rawa atu o 12 me 3 ko 12. Me tahuri \frac{5}{12} me \frac{1}{3} ki te hautau me te tautūnga 12.

$$\frac{5}{12}+\frac{4}{12}-\frac{1}{4}$$

Tā te mea he rite te tauraro o \frac{5}{12} me \frac{4}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{5+4}{12}-\frac{1}{4}$$

Tāpirihia te 5 ki te 4, ka 9.

$$\frac{9}{12}-\frac{1}{4}$$

Whakahekea te hautanga \frac{9}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{3}{4}-\frac{1}{4}$$

Tā te mea he rite te tauraro o \frac{3}{4} me \frac{1}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3-1}{4}$$

Tangohia te 1 i te 3, ka 2.

$$\frac{2}{4}$$

Whakahekea te hautanga \frac{2}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

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

Tauwehe

$$\frac{1}{2} = 0.5$$
