Whakaoti i te 5+((3/5)(-7))-(-1-8)

$$5 + ( ( 3 / 5 ) ( - 7 ) ) - ( - 1 - 8 )$$

Aromātai

$$\frac{49}{5}=9.8$$

Ngā Upane Otinga

Tuhia te \frac{3}{5}\left(-7\right) hei hautanga kotahi.

$$5+\frac{3\left(-7\right)}{5}-\left(-1-8\right)$$

Whakareatia te 3 ki te -7, ka -21.

$$5+\frac{-21}{5}-\left(-1-8\right)$$

Ka taea te hautanga \frac{-21}{5} te tuhi anō ko -\frac{21}{5} mā te tango i te tohu tōraro.

$$5-\frac{21}{5}-\left(-1-8\right)$$

Me tahuri te 5 ki te hautau \frac{25}{5}.

$$\frac{25}{5}-\frac{21}{5}-\left(-1-8\right)$$

Tā te mea he rite te tauraro o \frac{25}{5} me \frac{21}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{25-21}{5}-\left(-1-8\right)$$

Tangohia te 21 i te 25, ka 4.

$$\frac{4}{5}-\left(-1-8\right)$$

Tangohia te 8 i te -1, ka -9.

$$\frac{4}{5}-\left(-9\right)$$

Ko te tauaro o -9 ko 9.

$$\frac{4}{5}+9$$

Me tahuri te 9 ki te hautau \frac{45}{5}.

$$\frac{4}{5}+\frac{45}{5}$$

Tā te mea he rite te tauraro o \frac{4}{5} me \frac{45}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{4+45}{5}$$

Tāpirihia te 4 ki te 45, ka 49.

$$\frac{49}{5}$$

Tauwehe

$$\frac{7 ^ {2}}{5} = 9\frac{4}{5} = 9.8$$
