Whakaoti i te 24*12+1/2*2.1*44

$$24 \times 12 + \frac { 1 } { 2 } \times 2.1 \times 44$$

Aromātai

$$334.2$$

Ngā Upane Otinga

Whakareatia te 24 ki te 12, ka 288.

$$288+\frac{1}{2}\times 2.1\times 44$$

Me tahuri ki tau ā-ira 2.1 ki te hautau \frac{21}{10}.

$$288+\frac{1}{2}\times \frac{21}{10}\times 44$$

Me whakarea te \frac{1}{2} ki te \frac{21}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$288+\frac{1\times 21}{2\times 10}\times 44$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 21}{2\times 10}.

$$288+\frac{21}{20}\times 44$$

Tuhia te \frac{21}{20}\times 44 hei hautanga kotahi.

$$288+\frac{21\times 44}{20}$$

Whakareatia te 21 ki te 44, ka 924.

$$288+\frac{924}{20}$$

Whakahekea te hautanga \frac{924}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$288+\frac{231}{5}$$

Me tahuri te 288 ki te hautau \frac{1440}{5}.

$$\frac{1440}{5}+\frac{231}{5}$$

Tā te mea he rite te tauraro o \frac{1440}{5} me \frac{231}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1440+231}{5}$$

Tāpirihia te 1440 ki te 231, ka 1671.

$$\frac{1671}{5}$$

Tauwehe

$$\frac{3 \cdot 557}{5} = 334\frac{1}{5} = 334.2$$
