Whakaoti i te 1/5(-1+2(0.156)-3(-0.568))=

$$\frac { 1 } { 5 } ( - 1 + 2 ( 0.156 ) - 3 ( - 0.568 ) ) =$$

Aromātai

$$0.2032$$

Ngā Upane Otinga

Whakareatia te 2 ki te 0.156, ka 0.312.

$$\frac{1}{5}\left(-1+0.312-3\left(-0.568\right)\right)$$

Tāpirihia te -1 ki te 0.312, ka -0.688.

$$\frac{1}{5}\left(-0.688-3\left(-0.568\right)\right)$$

Whakareatia te 3 ki te -0.568, ka -1.704.

$$\frac{1}{5}\left(-0.688-\left(-1.704\right)\right)$$

Ko te tauaro o -1.704 ko 1.704.

$$\frac{1}{5}\left(-0.688+1.704\right)$$

Tāpirihia te -0.688 ki te 1.704, ka 1.016.

$$\frac{1}{5}\times 1.016$$

Me tahuri ki tau ā-ira 1.016 ki te hautau \frac{1016}{1000}. Whakahekea te hautanga \frac{1016}{1000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$\frac{1}{5}\times \frac{127}{125}$$

Me whakarea te \frac{1}{5} ki te \frac{127}{125} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 127}{5\times 125}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 127}{5\times 125}.

$$\frac{127}{625}$$

Tauwehe

$$\frac{127}{5 ^ {4}} = 0.2032$$
