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

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

Aromātai

$$\frac{133}{12}\approx 11.083333333$$

Ngā Upane Otinga

Whakawehea te 9 ki te 9, kia riro ko 1.

$$\frac{7}{2}\left(\frac{13}{6}+1\right)$$

Me tahuri te 1 ki te hautau \frac{6}{6}.

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

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

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

Tāpirihia te 13 ki te 6, ka 19.

$$\frac{7}{2}\times \frac{19}{6}$$

Me whakarea te \frac{7}{2} ki te \frac{19}{6} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7\times 19}{2\times 6}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 19}{2\times 6}.

$$\frac{133}{12}$$

Tauwehe

$$\frac{7 \cdot 19}{2 ^ {2} \cdot 3} = 11\frac{1}{12} = 11.083333333333334$$
