Whakaoti i te 4/5-5(1/3)+3/2

$$\frac{ 4 }{ 5 } -5( \frac{ 1 }{ 3 } )+ \frac{ 3 }{ 2 }$$

Aromātai

$$\frac{19}{30}\approx 0.633333333$$

Ngā Upane Otinga

Whakareatia te 5 ki te \frac{1}{3}, ka \frac{5}{3}.

$$\frac{4}{5}-\frac{5}{3}+\frac{3}{2}$$

Ko te maha noa iti rawa atu o 5 me 3 ko 15. Me tahuri \frac{4}{5} me \frac{5}{3} ki te hautau me te tautūnga 15.

$$\frac{12}{15}-\frac{25}{15}+\frac{3}{2}$$

Tā te mea he rite te tauraro o \frac{12}{15} me \frac{25}{15}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{12-25}{15}+\frac{3}{2}$$

Tangohia te 25 i te 12, ka -13.

$$-\frac{13}{15}+\frac{3}{2}$$

Ko te maha noa iti rawa atu o 15 me 2 ko 30. Me tahuri -\frac{13}{15} me \frac{3}{2} ki te hautau me te tautūnga 30.

$$-\frac{26}{30}+\frac{45}{30}$$

Tā te mea he rite te tauraro o -\frac{26}{30} me \frac{45}{30}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-26+45}{30}$$

Tāpirihia te -26 ki te 45, ka 19.

$$\frac{19}{30}$$

Tauwehe

$$\frac{19}{2 \cdot 3 \cdot 5} = 0.6333333333333333$$
