Whakaoti i te (-4)*left(1/3+3/8+2/5right)

$$(-4) \times \left( \frac{ 1 }{ 3 } + \frac{ 3 }{ 8 } + \frac{ 2 }{ 5 } \right)$$

Aromātai

$$-\frac{133}{30}\approx -4.433333333$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 8 ko 24. Me tahuri \frac{1}{3} me \frac{3}{8} ki te hautau me te tautūnga 24.

$$-4\left(\frac{8}{24}+\frac{9}{24}+\frac{2}{5}\right)$$

Tā te mea he rite te tauraro o \frac{8}{24} me \frac{9}{24}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$-4\left(\frac{8+9}{24}+\frac{2}{5}\right)$$

Tāpirihia te 8 ki te 9, ka 17.

$$-4\left(\frac{17}{24}+\frac{2}{5}\right)$$

Ko te maha noa iti rawa atu o 24 me 5 ko 120. Me tahuri \frac{17}{24} me \frac{2}{5} ki te hautau me te tautūnga 120.

$$-4\left(\frac{85}{120}+\frac{48}{120}\right)$$

Tā te mea he rite te tauraro o \frac{85}{120} me \frac{48}{120}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$-4\times \frac{85+48}{120}$$

Tāpirihia te 85 ki te 48, ka 133.

$$-4\times \frac{133}{120}$$

Tuhia te -4\times \frac{133}{120} hei hautanga kotahi.

$$\frac{-4\times 133}{120}$$

Whakareatia te -4 ki te 133, ka -532.

$$\frac{-532}{120}$$

Whakahekea te hautanga \frac{-532}{120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$-\frac{133}{30}$$

Tauwehe

$$-\frac{133}{30} = -4\frac{13}{30} = -4.433333333333334$$
