Whakaoti i te (-1/3-1/2)div5/4

$$(- \frac{ 1 }{ 3 } - \frac{ 1 }{ 2 } ) \div \frac{ 5 }{ 4 }$$

Aromātai

$$-\frac{2}{3}\approx -0.666666667$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 2 ko 6. Me tahuri -\frac{1}{3} me \frac{1}{2} ki te hautau me te tautūnga 6.

$$\frac{-\frac{2}{6}-\frac{3}{6}}{\frac{5}{4}}$$

Tā te mea he rite te tauraro o -\frac{2}{6} me \frac{3}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{-2-3}{6}}{\frac{5}{4}}$$

Tangohia te 3 i te -2, ka -5.

$$\frac{-\frac{5}{6}}{\frac{5}{4}}$$

Whakawehe -\frac{5}{6} ki te \frac{5}{4} mā te whakarea -\frac{5}{6} ki te tau huripoki o \frac{5}{4}.

$$-\frac{5}{6}\times \frac{4}{5}$$

Me whakarea te -\frac{5}{6} ki te \frac{4}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-5\times 4}{6\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{-5\times 4}{6\times 5}.

$$\frac{-20}{30}$$

Whakahekea te hautanga \frac{-20}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$-\frac{2}{3}$$

Tauwehe

$$-\frac{2}{3} = -0.6666666666666666$$
