Whakaoti i te 5-4+0.3*3/2

$$5-4+0.3 \times \frac{ 3 }{ 2 }$$

Aromātai

$$1.45$$

Ngā Upane Otinga

Tangohia te 4 i te 5, ka 1.

$$1+0.3\times \frac{3}{2}$$

Me tahuri ki tau ā-ira 0.3 ki te hautau \frac{3}{10}.

$$1+\frac{3}{10}\times \frac{3}{2}$$

Me whakarea te \frac{3}{10} ki te \frac{3}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$1+\frac{3\times 3}{10\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 3}{10\times 2}.

$$1+\frac{9}{20}$$

Me tahuri te 1 ki te hautau \frac{20}{20}.

$$\frac{20}{20}+\frac{9}{20}$$

Tā te mea he rite te tauraro o \frac{20}{20} me \frac{9}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{20+9}{20}$$

Tāpirihia te 20 ki te 9, ka 29.

$$\frac{29}{20}$$

Tauwehe

$$\frac{29}{5 \cdot 2 ^ {2}} = 1\frac{9}{20} = 1.45$$
