Whakaoti i te 4-3(4/3-3/2)

$$4 - 3 ( \frac { 4 } { 3 } - \frac { 3 } { 2 } )$$

Aromātai

$$\frac{9}{2}=4.5$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 2 ko 6. Me tahuri \frac{4}{3} me \frac{3}{2} ki te hautau me te tautūnga 6.

$$4-3\left(\frac{8}{6}-\frac{9}{6}\right)$$

Tā te mea he rite te tauraro o \frac{8}{6} me \frac{9}{6}, me tango rāua mā te tango i ō raua taurunga.

$$4-3\times \frac{8-9}{6}$$

Tangohia te 9 i te 8, ka -1.

$$4-3\left(-\frac{1}{6}\right)$$

Tuhia te 3\left(-\frac{1}{6}\right) hei hautanga kotahi.

$$4-\frac{3\left(-1\right)}{6}$$

Whakareatia te 3 ki te -1, ka -3.

$$4-\frac{-3}{6}$$

Whakahekea te hautanga \frac{-3}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$4-\left(-\frac{1}{2}\right)$$

Ko te tauaro o -\frac{1}{2} ko \frac{1}{2}.

$$4+\frac{1}{2}$$

Me tahuri te 4 ki te hautau \frac{8}{2}.

$$\frac{8}{2}+\frac{1}{2}$$

Tā te mea he rite te tauraro o \frac{8}{2} me \frac{1}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{8+1}{2}$$

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{9}{2}$$

Tauwehe

$$\frac{3 ^ {2}}{2} = 4\frac{1}{2} = 4.5$$
