Whakaoti i te 3/4(-10+2/5)quad{l}{text{per}h}{text{man}}{text{entir}}

$$\frac { 3 } { 4 } ( - 10 + \frac { 2 } { 5 } ) \quad \left. \begin{array} { l } { \text { per } h } \\ { \text { man } } \\ { \text { entir } } \end{array} \right.$$

$$-\frac{36}{5}=-7.2$$

Ngā Upane Otinga

Me tahuri te -10 ki te hautau -\frac{50}{5}.

$$\frac{3}{4}\left(-\frac{50}{5}+\frac{2}{5}\right)$$

Tā te mea he rite te tauraro o -\frac{50}{5} me \frac{2}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3}{4}\times \frac{-50+2}{5}$$

Tāpirihia te -50 ki te 2, ka -48.

$$\frac{3}{4}\left(-\frac{48}{5}\right)$$

Me whakarea te \frac{3}{4} ki te -\frac{48}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3\left(-48\right)}{4\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\left(-48\right)}{4\times 5}.

$$\frac{-144}{20}$$

Whakahekea te hautanga \frac{-144}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$-\frac{36}{5}$$

Tauwehe

$$-\frac{36}{5} = -7\frac{1}{5} = -7.2$$
