Whakaoti i te 0.75+5/6*(-2/3)=

$$0.75 + \frac { 5 } { 6 } \times ( - \frac { 2 } { 3 } ) =$$

Aromātai

$$\frac{7}{36}\approx 0.194444444$$

Ngā Upane Otinga

Me whakarea te \frac{5}{6} ki te -\frac{2}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$0.75+\frac{5\left(-2\right)}{6\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{5\left(-2\right)}{6\times 3}.

$$0.75+\frac{-10}{18}$$

Whakahekea te hautanga \frac{-10}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$0.75-\frac{5}{9}$$

Me tahuri ki tau ā-ira 0.75 ki te hautau \frac{75}{100}. Whakahekea te hautanga \frac{75}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{3}{4}-\frac{5}{9}$$

Ko te maha noa iti rawa atu o 4 me 9 ko 36. Me tahuri \frac{3}{4} me \frac{5}{9} ki te hautau me te tautūnga 36.

$$\frac{27}{36}-\frac{20}{36}$$

Tā te mea he rite te tauraro o \frac{27}{36} me \frac{20}{36}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{27-20}{36}$$

Tangohia te 20 i te 27, ka 7.

$$\frac{7}{36}$$

Tauwehe

$$\frac{7}{2 ^ {2} \cdot 3 ^ {2}} = 0.19444444444444445$$
