Aromātai

$$55.86$$

Ngā Upane Otinga

Whakawehe \frac{11}{5} ki te \frac{4}{25} mā te whakarea \frac{11}{5} ki te tau huripoki o \frac{4}{25}.

$$2.11+\frac{11}{5}\times \frac{25}{4}+40$$

Me whakarea te \frac{11}{5} ki te \frac{25}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$2.11+\frac{11\times 25}{5\times 4}+40$$

Mahia ngā whakarea i roto i te hautanga \frac{11\times 25}{5\times 4}.

$$2.11+\frac{275}{20}+40$$

Whakahekea te hautanga \frac{275}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$2.11+\frac{55}{4}+40$$

Me tahuri ki tau ā-ira 2.11 ki te hautau \frac{211}{100}.

$$\frac{211}{100}+\frac{55}{4}+40$$

Ko te maha noa iti rawa atu o 100 me 4 ko 100. Me tahuri \frac{211}{100} me \frac{55}{4} ki te hautau me te tautūnga 100.

$$\frac{211}{100}+\frac{1375}{100}+40$$

Tā te mea he rite te tauraro o \frac{211}{100} me \frac{1375}{100}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{211+1375}{100}+40$$

Tāpirihia te 211 ki te 1375, ka 1586.

$$\frac{1586}{100}+40$$

Whakahekea te hautanga \frac{1586}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{793}{50}+40$$

Me tahuri te 40 ki te hautau \frac{2000}{50}.

$$\frac{793}{50}+\frac{2000}{50}$$

Tā te mea he rite te tauraro o \frac{793}{50} me \frac{2000}{50}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{793+2000}{50}$$

Tāpirihia te 793 ki te 2000, ka 2793.

$$\frac{2793}{50}$$

Tauwehe

$$\frac{3 \cdot 19 \cdot 7 ^ {2}}{2 \cdot 5 ^ {2}} = 55\frac{43}{50} = 55.86$$
