Whakaoti i te 4+4/5(-5/2)3+2div2/3-2left(1/2-frac{2}{3}right)

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

Aromātai

$$\frac{4}{3}\approx 1.333333333$$

Ngā Upane Otinga

Me whakarea te \frac{4}{5} ki te -\frac{5}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$4+\frac{4\left(-5\right)}{5\times 2}\times 3+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{4\left(-5\right)}{5\times 2}.

$$4+\frac{-20}{10}\times 3+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Whakawehea te -20 ki te 10, kia riro ko -2.

$$4-2\times 3+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Whakareatia te -2 ki te 3, ka -6.

$$4-6+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Tangohia te 6 i te 4, ka -2.

$$-2+\frac{2}{\frac{2}{3}}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Whakawehe 2 ki te \frac{2}{3} mā te whakarea 2 ki te tau huripoki o \frac{2}{3}.

$$-2+2\times \frac{3}{2}-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Me whakakore te 2 me te 2.

$$-2+3-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

Tāpirihia te -2 ki te 3, ka 1.

$$1-2\left(\frac{1}{2}-\frac{2}{3}\right)$$

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

$$1-2\left(\frac{3}{6}-\frac{4}{6}\right)$$

Tā te mea he rite te tauraro o \frac{3}{6} me \frac{4}{6}, me tango rāua mā te tango i ō raua taurunga.

$$1-2\times \frac{3-4}{6}$$

Tangohia te 4 i te 3, ka -1.

$$1-2\left(-\frac{1}{6}\right)$$

Tuhia te 2\left(-\frac{1}{6}\right) hei hautanga kotahi.

$$1-\frac{2\left(-1\right)}{6}$$

Whakareatia te 2 ki te -1, ka -2.

$$1-\frac{-2}{6}$$

Whakahekea te hautanga \frac{-2}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$1-\left(-\frac{1}{3}\right)$$

Ko te tauaro o -\frac{1}{3} ko \frac{1}{3}.

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

Me tahuri te 1 ki te hautau \frac{3}{3}.

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

Tā te mea he rite te tauraro o \frac{3}{3} me \frac{1}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Tāpirihia te 3 ki te 1, ka 4.

$$\frac{4}{3}$$

Tauwehe

$$\frac{2 ^ {2}}{3} = 1\frac{1}{3} = 1.3333333333333333$$
