Whakaoti i te 41/2*13/4

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

Aromātai

$$\frac{63}{8}=7.875$$

Ngā Upane Otinga

Whakareatia te 4 ki te 2, ka 8.

$$\frac{8+1}{2}\times \frac{1\times 4+3}{4}$$

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{9}{2}\times \frac{1\times 4+3}{4}$$

Whakareatia te 1 ki te 4, ka 4.

$$\frac{9}{2}\times \frac{4+3}{4}$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{9}{2}\times \frac{7}{4}$$

Me whakarea te \frac{9}{2} ki te \frac{7}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{9\times 7}{2\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{9\times 7}{2\times 4}.

$$\frac{63}{8}$$

Tauwehe

$$\frac{3 ^ {2} \cdot 7}{2 ^ {3}} = 7\frac{7}{8} = 7.875$$
