Whakaoti i te (3/4+23/8)*258

$$( \frac{ 3 }{ 4 } + 2 \frac { 3 } { 8 } ) \times 258$$

Aromātai

$$\frac{3225}{4}=806.25$$

Ngā Upane Otinga

Whakareatia te 2 ki te 8, ka 16.

$$\left(\frac{3}{4}+\frac{16+3}{8}\right)\times 258$$

Tāpirihia te 16 ki te 3, ka 19.

$$\left(\frac{3}{4}+\frac{19}{8}\right)\times 258$$

Ko te maha noa iti rawa atu o 4 me 8 ko 8. Me tahuri \frac{3}{4} me \frac{19}{8} ki te hautau me te tautūnga 8.

$$\left(\frac{6}{8}+\frac{19}{8}\right)\times 258$$

Tā te mea he rite te tauraro o \frac{6}{8} me \frac{19}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{6+19}{8}\times 258$$

Tāpirihia te 6 ki te 19, ka 25.

$$\frac{25}{8}\times 258$$

Tuhia te \frac{25}{8}\times 258 hei hautanga kotahi.

$$\frac{25\times 258}{8}$$

Whakareatia te 25 ki te 258, ka 6450.

$$\frac{6450}{8}$$

Whakahekea te hautanga \frac{6450}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{3225}{4}$$

Tauwehe

$$\frac{3 \cdot 5 ^ {2} \cdot 43}{2 ^ {2}} = 806\frac{1}{4} = 806.25$$
