Whakaoti i te 71/2*(3div5/9)

$$7 \frac { 1 } { 2 } \cdot ( 3 \div \frac { 5 } { 9 } )$$

Aromātai

$$\frac{81}{2}=40.5$$

Ngā Upane Otinga

Whakareatia te 7 ki te 2, ka 14.

$$\frac{14+1}{2}\times \frac{3}{\frac{5}{9}}$$

Tāpirihia te 14 ki te 1, ka 15.

$$\frac{15}{2}\times \frac{3}{\frac{5}{9}}$$

Whakawehe 3 ki te \frac{5}{9} mā te whakarea 3 ki te tau huripoki o \frac{5}{9}.

$$\frac{15}{2}\times 3\times \frac{9}{5}$$

Tuhia te 3\times \frac{9}{5} hei hautanga kotahi.

$$\frac{15}{2}\times \frac{3\times 9}{5}$$

Whakareatia te 3 ki te 9, ka 27.

$$\frac{15}{2}\times \frac{27}{5}$$

Me whakarea te \frac{15}{2} ki te \frac{27}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{15\times 27}{2\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{15\times 27}{2\times 5}.

$$\frac{405}{10}$$

Whakahekea te hautanga \frac{405}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{81}{2}$$

Tauwehe

$$\frac{3 ^ {4}}{2} = 40\frac{1}{2} = 40.5$$
