Whakaoti i te (-1/5-1)*(-2+1/2)

$$(- \frac{ 1 }{ 5 } -1) \times (-2+ \frac{ 1 }{ 2 } )$$

Aromātai

$$\frac{9}{5}=1.8$$

Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{5}{5}.

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

Tā te mea he rite te tauraro o -\frac{1}{5} me \frac{5}{5}, me tango rāua mā te tango i ō raua taurunga.

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

Tangohia te 5 i te -1, ka -6.

$$-\frac{6}{5}\left(-2+\frac{1}{2}\right)$$

Me tahuri te -2 ki te hautau -\frac{4}{2}.

$$-\frac{6}{5}\left(-\frac{4}{2}+\frac{1}{2}\right)$$

Tā te mea he rite te tauraro o -\frac{4}{2} me \frac{1}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$-\frac{6}{5}\times \frac{-4+1}{2}$$

Tāpirihia te -4 ki te 1, ka -3.

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

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

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

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

$$\frac{18}{10}$$

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

$$\frac{9}{5}$$

Tauwehe

$$\frac{3 ^ {2}}{5} = 1\frac{4}{5} = 1.8$$
