Whakaoti i te 3+1/5*7/2

$$3 + \frac { 1 } { 5 } \cdot \frac { 7 } { 2 }$$

Aromātai

$$\frac{37}{10}=3.7$$

Ngā Upane Otinga

Me whakarea te \frac{1}{5} ki te \frac{7}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$3+\frac{1\times 7}{5\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 7}{5\times 2}.

$$3+\frac{7}{10}$$

Me tahuri te 3 ki te hautau \frac{30}{10}.

$$\frac{30}{10}+\frac{7}{10}$$

Tā te mea he rite te tauraro o \frac{30}{10} me \frac{7}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{30+7}{10}$$

Tāpirihia te 30 ki te 7, ka 37.

$$\frac{37}{10}$$

Tauwehe

$$\frac{37}{2 \cdot 5} = 3\frac{7}{10} = 3.7$$
