Whakaoti i te 1.68+2.16-1.92/4*(0.975*200-192)

$$1.68+ \frac{ 2.16-1.92 }{ 4 } \times (0.975 \times 200-192)$$

Aromātai

$$1.86$$

Ngā Upane Otinga

Tangohia te 1.92 i te 2.16, ka 0.24.

$$1.68+\frac{0.24}{4}\left(0.975\times 200-192\right)$$

Whakarohaina te \frac{0.24}{4} mā te whakarea i te taurunga me te tauraro ki te 100.

$$1.68+\frac{24}{400}\left(0.975\times 200-192\right)$$

Whakahekea te hautanga \frac{24}{400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$1.68+\frac{3}{50}\left(0.975\times 200-192\right)$$

Whakareatia te 0.975 ki te 200, ka 195.

$$1.68+\frac{3}{50}\left(195-192\right)$$

Tangohia te 192 i te 195, ka 3.

$$1.68+\frac{3}{50}\times 3$$

Tuhia te \frac{3}{50}\times 3 hei hautanga kotahi.

$$1.68+\frac{3\times 3}{50}$$

Whakareatia te 3 ki te 3, ka 9.

$$1.68+\frac{9}{50}$$

Me tahuri ki tau ā-ira 1.68 ki te hautau \frac{168}{100}. Whakahekea te hautanga \frac{168}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{42}{25}+\frac{9}{50}$$

Ko te maha noa iti rawa atu o 25 me 50 ko 50. Me tahuri \frac{42}{25} me \frac{9}{50} ki te hautau me te tautūnga 50.

$$\frac{84}{50}+\frac{9}{50}$$

Tā te mea he rite te tauraro o \frac{84}{50} me \frac{9}{50}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{84+9}{50}$$

Tāpirihia te 84 ki te 9, ka 93.

$$\frac{93}{50}$$

Tauwehe

$$\frac{3 \cdot 31}{2 \cdot 5 ^ {2}} = 1\frac{43}{50} = 1.86$$
