Whakaoti i te 127-(30/5+422/6)

$$127 - ( \frac { 30 } { 5 } + 42 \frac { 2 } { 6 } )$$

Aromātai

$$\frac{236}{3}\approx 78.666666667$$

Ngā Upane Otinga

Whakawehea te 30 ki te 5, kia riro ko 6.

$$127-\left(6+\frac{42\times 6+2}{6}\right)$$

Whakareatia te 42 ki te 6, ka 252.

$$127-\left(6+\frac{252+2}{6}\right)$$

Tāpirihia te 252 ki te 2, ka 254.

$$127-\left(6+\frac{254}{6}\right)$$

Whakahekea te hautanga \frac{254}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$127-\left(6+\frac{127}{3}\right)$$

Me tahuri te 6 ki te hautau \frac{18}{3}.

$$127-\left(\frac{18}{3}+\frac{127}{3}\right)$$

Tā te mea he rite te tauraro o \frac{18}{3} me \frac{127}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$127-\frac{18+127}{3}$$

Tāpirihia te 18 ki te 127, ka 145.

$$127-\frac{145}{3}$$

Me tahuri te 127 ki te hautau \frac{381}{3}.

$$\frac{381}{3}-\frac{145}{3}$$

Tā te mea he rite te tauraro o \frac{381}{3} me \frac{145}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{381-145}{3}$$

Tangohia te 145 i te 381, ka 236.

$$\frac{236}{3}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 59}{3} = 78\frac{2}{3} = 78.66666666666667$$
