$$\frac{221}{90}\approx 2.455555556$$

Ngā Upane Otinga

Whakareatia te 5 ki te 3, ka 15.

$$\frac{\frac{15+2}{3}\times 0.4}{1.02}+\frac{0.28}{1.2}$$

Tāpirihia te 15 ki te 2, ka 17.

$$\frac{\frac{17}{3}\times 0.4}{1.02}+\frac{0.28}{1.2}$$

Me tahuri ki tau ā-ira 0.4 ki te hautau \frac{4}{10}. Whakahekea te hautanga \frac{4}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{\frac{17}{3}\times \frac{2}{5}}{1.02}+\frac{0.28}{1.2}$$

Me whakarea te \frac{17}{3} ki te \frac{2}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\frac{17\times 2}{3\times 5}}{1.02}+\frac{0.28}{1.2}$$

Mahia ngā whakarea i roto i te hautanga \frac{17\times 2}{3\times 5}.

$$\frac{\frac{34}{15}}{1.02}+\frac{0.28}{1.2}$$

Tuhia te \frac{\frac{34}{15}}{1.02} hei hautanga kotahi.

$$\frac{34}{15\times 1.02}+\frac{0.28}{1.2}$$

Whakareatia te 15 ki te 1.02, ka 15.3.

$$\frac{34}{15.3}+\frac{0.28}{1.2}$$

Whakarohaina te \frac{34}{15.3} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{340}{153}+\frac{0.28}{1.2}$$

Whakahekea te hautanga \frac{340}{153} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 17.

$$\frac{20}{9}+\frac{0.28}{1.2}$$

Whakarohaina te \frac{0.28}{1.2} mā te whakarea i te taurunga me te tauraro ki te 100.

$$\frac{20}{9}+\frac{28}{120}$$

Whakahekea te hautanga \frac{28}{120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{20}{9}+\frac{7}{30}$$

Ko te maha noa iti rawa atu o 9 me 30 ko 90. Me tahuri \frac{20}{9} me \frac{7}{30} ki te hautau me te tautūnga 90.

$$\frac{200}{90}+\frac{21}{90}$$

Tā te mea he rite te tauraro o \frac{200}{90} me \frac{21}{90}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{200+21}{90}$$

Tāpirihia te 200 ki te 21, ka 221.

$$\frac{221}{90}$$

Tauwehe

$$\frac{13 \cdot 17}{2 \cdot 5 \cdot 3 ^ {2}} = 2\frac{41}{90} = 2.4555555555555557$$
