$$- \frac { 7 } { 8 } - ( - \frac { 5 } { 6 } ) + \frac { 1 } { 3 }$$

Aromātai

$$\frac{7}{24}\approx 0.291666667$$

Ngā Upane Otinga

Ko te tauaro o -\frac{5}{6} ko \frac{5}{6}.

$$-\frac{7}{8}+\frac{5}{6}+\frac{1}{3}$$

Ko te maha noa iti rawa atu o 8 me 6 ko 24. Me tahuri -\frac{7}{8} me \frac{5}{6} ki te hautau me te tautūnga 24.

$$-\frac{21}{24}+\frac{20}{24}+\frac{1}{3}$$

Tā te mea he rite te tauraro o -\frac{21}{24} me \frac{20}{24}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-21+20}{24}+\frac{1}{3}$$

Tāpirihia te -21 ki te 20, ka -1.

$$-\frac{1}{24}+\frac{1}{3}$$

Ko te maha noa iti rawa atu o 24 me 3 ko 24. Me tahuri -\frac{1}{24} me \frac{1}{3} ki te hautau me te tautūnga 24.

$$-\frac{1}{24}+\frac{8}{24}$$

Tā te mea he rite te tauraro o -\frac{1}{24} me \frac{8}{24}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1+8}{24}$$

Tāpirihia te -1 ki te 8, ka 7.

$$\frac{7}{24}$$

Tauwehe

$$\frac{7}{2 ^ {3} \cdot 3} = 0.2916666666666667$$
