Whakaoti i te 47/2*62/8=

$$4 \frac { 7 } { 2 } \times 6 \frac { 2 } { 8 } =$$

Aromātai

$$\frac{375}{8}=46.875$$

Ngā Upane Otinga

Whakareatia te 4 ki te 2, ka 8.

$$\frac{8+7}{2}\times \frac{6\times 8+2}{8}$$

Tāpirihia te 8 ki te 7, ka 15.

$$\frac{15}{2}\times \frac{6\times 8+2}{8}$$

Whakareatia te 6 ki te 8, ka 48.

$$\frac{15}{2}\times \frac{48+2}{8}$$

Tāpirihia te 48 ki te 2, ka 50.

$$\frac{15}{2}\times \frac{50}{8}$$

Whakahekea te hautanga \frac{50}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{15}{2}\times \frac{25}{4}$$

Me whakarea te \frac{15}{2} ki te \frac{25}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{15\times 25}{2\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{15\times 25}{2\times 4}.

$$\frac{375}{8}$$

Tauwehe

$$\frac{3 \cdot 5 ^ {3}}{2 ^ {3}} = 46\frac{7}{8} = 46.875$$
