Whakaoti i te 7/2*(13/6+9)

$$\frac { 7 } { 2 } \cdot ( \frac { 13 } { 6 } + 9 )$$

Aromātai

$$\frac{469}{12}\approx 39.083333333$$

Ngā Upane Otinga

Me tahuri te 9 ki te hautau \frac{54}{6}.

$$\frac{7}{2}\left(\frac{13}{6}+\frac{54}{6}\right)$$

Tā te mea he rite te tauraro o \frac{13}{6} me \frac{54}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{7}{2}\times \frac{13+54}{6}$$

Tāpirihia te 13 ki te 54, ka 67.

$$\frac{7}{2}\times \frac{67}{6}$$

Me whakarea te \frac{7}{2} ki te \frac{67}{6} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7\times 67}{2\times 6}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 67}{2\times 6}.

$$\frac{469}{12}$$

Tauwehe

$$\frac{7 \cdot 67}{2 ^ {2} \cdot 3} = 39\frac{1}{12} = 39.083333333333336$$
