$$- \frac { 8 } { 7 } - \frac { 1 } { 5 } - \frac { 3 } { 4 } ( \frac { 293 } { 140 } )$$

Aromātai

$$-\frac{233}{80}=-2.9125$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 7 me 5 ko 35. Me tahuri -\frac{8}{7} me \frac{1}{5} ki te hautau me te tautūnga 35.

$$-\frac{40}{35}-\frac{7}{35}-\frac{3}{4}\times \frac{293}{140}$$

Tā te mea he rite te tauraro o -\frac{40}{35} me \frac{7}{35}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-40-7}{35}-\frac{3}{4}\times \frac{293}{140}$$

Tangohia te 7 i te -40, ka -47.

$$-\frac{47}{35}-\frac{3}{4}\times \frac{293}{140}$$

Me whakarea te \frac{3}{4} ki te \frac{293}{140} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$-\frac{47}{35}-\frac{3\times 293}{4\times 140}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 293}{4\times 140}.

$$-\frac{47}{35}-\frac{879}{560}$$

Ko te maha noa iti rawa atu o 35 me 560 ko 560. Me tahuri -\frac{47}{35} me \frac{879}{560} ki te hautau me te tautūnga 560.

$$-\frac{752}{560}-\frac{879}{560}$$

Tā te mea he rite te tauraro o -\frac{752}{560} me \frac{879}{560}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-752-879}{560}$$

Tangohia te 879 i te -752, ka -1631.

$$\frac{-1631}{560}$$

Whakahekea te hautanga \frac{-1631}{560} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$-\frac{233}{80}$$

Tauwehe

$$-\frac{233}{80} = -2\frac{73}{80} = -2.9125$$
