Whakaoti i te 3-(14/15+7/10)

$$3-( \frac{ 14 }{ 15 } + \frac{ 7 }{ 10 } )$$

Aromātai

$$\frac{41}{30}\approx 1.366666667$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 15 me 10 ko 30. Me tahuri \frac{14}{15} me \frac{7}{10} ki te hautau me te tautūnga 30.

$$3-\left(\frac{28}{30}+\frac{21}{30}\right)$$

Tā te mea he rite te tauraro o \frac{28}{30} me \frac{21}{30}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$3-\frac{28+21}{30}$$

Tāpirihia te 28 ki te 21, ka 49.

$$3-\frac{49}{30}$$

Me tahuri te 3 ki te hautau \frac{90}{30}.

$$\frac{90}{30}-\frac{49}{30}$$

Tā te mea he rite te tauraro o \frac{90}{30} me \frac{49}{30}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{90-49}{30}$$

Tangohia te 49 i te 90, ka 41.

$$\frac{41}{30}$$

Tauwehe

$$\frac{41}{2 \cdot 3 \cdot 5} = 1\frac{11}{30} = 1.3666666666666667$$
