Whakaoti i te 13/4*21/3=

$$1 \frac { 3 } { 4 } \times 2 \frac { 1 } { 3 } =$$

Aromātai

$$\frac{49}{12}\approx 4.083333333$$

Ngā Upane Otinga

Whakareatia te 1 ki te 4, ka 4.

$$\frac{4+3}{4}\times \frac{2\times 3+1}{3}$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{7}{4}\times \frac{2\times 3+1}{3}$$

Whakareatia te 2 ki te 3, ka 6.

$$\frac{7}{4}\times \frac{6+1}{3}$$

Tāpirihia te 6 ki te 1, ka 7.

$$\frac{7}{4}\times \frac{7}{3}$$

Me whakarea te \frac{7}{4} ki te \frac{7}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7\times 7}{4\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 7}{4\times 3}.

$$\frac{49}{12}$$

Tauwehe

$$\frac{7 ^ {2}}{2 ^ {2} \cdot 3} = 4\frac{1}{12} = 4.083333333333333$$
