Whakaoti i te 23div32/7*13/4

$$23 \div 3 \frac { 2 } { 7 } \times 1 \frac { 3 } { 4 }$$

Aromātai

$$\frac{49}{4}=12.25$$

Ngā Upane Otinga

Whakawehe 23 ki te \frac{3\times 7+2}{7} mā te whakarea 23 ki te tau huripoki o \frac{3\times 7+2}{7}.

$$\frac{23\times 7}{3\times 7+2}\times \frac{1\times 4+3}{4}$$

Whakareatia te 23 ki te 7, ka 161.

$$\frac{161}{3\times 7+2}\times \frac{1\times 4+3}{4}$$

Whakareatia te 3 ki te 7, ka 21.

$$\frac{161}{21+2}\times \frac{1\times 4+3}{4}$$

Tāpirihia te 21 ki te 2, ka 23.

$$\frac{161}{23}\times \frac{1\times 4+3}{4}$$

Whakawehea te 161 ki te 23, kia riro ko 7.

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

Whakareatia te 1 ki te 4, ka 4.

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

Tāpirihia te 4 ki te 3, ka 7.

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

Tuhia te 7\times \frac{7}{4} hei hautanga kotahi.

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

Whakareatia te 7 ki te 7, ka 49.

$$\frac{49}{4}$$

Tauwehe

$$\frac{7 ^ {2}}{2 ^ {2}} = 12\frac{1}{4} = 12.25$$
