Whakaoti i te 1.1*2.5+1.1^2:11

$$1.1 \cdot 2.5 + 1.1 ^ { 2 } : 11$$

Aromātai

$$2.86$$

Ngā Upane Otinga

Whakareatia te 1.1 ki te 2.5, ka 2.75.

$$2.75+\frac{1.1^{2}}{11}$$

Tātaihia te 1.1 mā te pū o 2, kia riro ko 1.21.

$$2.75+\frac{1.21}{11}$$

Whakarohaina te \frac{1.21}{11} mā te whakarea i te taurunga me te tauraro ki te 100.

$$2.75+\frac{121}{1100}$$

Whakahekea te hautanga \frac{121}{1100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 11.

$$2.75+\frac{11}{100}$$

Me tahuri ki tau ā-ira 2.75 ki te hautau \frac{275}{100}. Whakahekea te hautanga \frac{275}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{11}{4}+\frac{11}{100}$$

Ko te maha noa iti rawa atu o 4 me 100 ko 100. Me tahuri \frac{11}{4} me \frac{11}{100} ki te hautau me te tautūnga 100.

$$\frac{275}{100}+\frac{11}{100}$$

Tā te mea he rite te tauraro o \frac{275}{100} me \frac{11}{100}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{275+11}{100}$$

Tāpirihia te 275 ki te 11, ka 286.

$$\frac{286}{100}$$

Whakahekea te hautanga \frac{286}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{143}{50}$$

Tauwehe

$$\frac{11 \cdot 13}{2 \cdot 5 ^ {2}} = 2\frac{43}{50} = 2.86$$
