Ngā Upane Otinga

Me tahuri ki tau ā-ira -0.02 ki te hautau -\frac{2}{100}. Whakahekea te hautanga -\frac{2}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{4}\left(-\frac{1}{50}\right)+2$$

Me whakarea te \frac{1}{4} ki te -\frac{1}{50} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\left(-1\right)}{4\times 50}+2$$

Mahia ngā whakarea i roto i te hautanga \frac{1\left(-1\right)}{4\times 50}.

$$\frac{-1}{200}+2$$

Ka taea te hautanga \frac{-1}{200} te tuhi anō ko -\frac{1}{200} mā te tango i te tohu tōraro.

$$-\frac{1}{200}+2$$

Me tahuri te 2 ki te hautau \frac{400}{200}.

$$-\frac{1}{200}+\frac{400}{200}$$

Tā te mea he rite te tauraro o -\frac{1}{200} me \frac{400}{200}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1+400}{200}$$

Tāpirihia te -1 ki te 400, ka 399.

$$\frac{399}{200}$$

Tauwehe

$$\frac{3 \cdot 7 \cdot 19}{2 ^ {3} \cdot 5 ^ {2}} = 1\frac{199}{200} = 1.995$$
