Whakaoti i te 13/4+(-625)-(-27/8)-175

$$1 \frac { 3 } { 4 } + ( - 625 ) - ( - \frac { 27 } { 8 } ) - 175$$

Aromātai

$$-\frac{6359}{8}=-794.875$$

Ngā Upane Otinga

Whakareatia te 1 ki te 4, ka 4.

$$\frac{4+3}{4}-625-\left(-\frac{27}{8}\right)-175$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{7}{4}-625-\left(-\frac{27}{8}\right)-175$$

Me tahuri te 625 ki te hautau \frac{2500}{4}.

$$\frac{7}{4}-\frac{2500}{4}-\left(-\frac{27}{8}\right)-175$$

Tā te mea he rite te tauraro o \frac{7}{4} me \frac{2500}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{7-2500}{4}-\left(-\frac{27}{8}\right)-175$$

Tangohia te 2500 i te 7, ka -2493.

$$-\frac{2493}{4}-\left(-\frac{27}{8}\right)-175$$

Ko te tauaro o -\frac{27}{8} ko \frac{27}{8}.

$$-\frac{2493}{4}+\frac{27}{8}-175$$

Ko te maha noa iti rawa atu o 4 me 8 ko 8. Me tahuri -\frac{2493}{4} me \frac{27}{8} ki te hautau me te tautūnga 8.

$$-\frac{4986}{8}+\frac{27}{8}-175$$

Tā te mea he rite te tauraro o -\frac{4986}{8} me \frac{27}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-4986+27}{8}-175$$

Tāpirihia te -4986 ki te 27, ka -4959.

$$-\frac{4959}{8}-175$$

Me tahuri te 175 ki te hautau \frac{1400}{8}.

$$-\frac{4959}{8}-\frac{1400}{8}$$

Tā te mea he rite te tauraro o -\frac{4959}{8} me \frac{1400}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-4959-1400}{8}$$

Tangohia te 1400 i te -4959, ka -6359.

$$-\frac{6359}{8}$$

Tauwehe

$$-\frac{6359}{8} = -794\frac{7}{8} = -794.875$$
