Whakaoti i te 4div2/3div9/20

$$4 \div \frac { 2 } { 3 } \div \frac { 9 } { 20 }$$

Aromātai

$$\frac{40}{3}\approx 13.333333333$$

Ngā Upane Otinga

Whakawehe \frac{4}{\frac{2}{3}} ki te \frac{9}{20} mā te whakarea \frac{4}{\frac{2}{3}} ki te tau huripoki o \frac{9}{20}.

$$\frac{4\times 20}{\frac{2}{3}\times 9}$$

Whakareatia te 4 ki te 20, ka 80.

$$\frac{80}{\frac{2}{3}\times 9}$$

Tuhia te \frac{2}{3}\times 9 hei hautanga kotahi.

$$\frac{80}{\frac{2\times 9}{3}}$$

Whakareatia te 2 ki te 9, ka 18.

$$\frac{80}{\frac{18}{3}}$$

Whakawehea te 18 ki te 3, kia riro ko 6.

$$\frac{80}{6}$$

Whakahekea te hautanga \frac{80}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{40}{3}$$

Tauwehe

$$\frac{2 ^ {3} \cdot 5}{3} = 13\frac{1}{3} = 13.333333333333334$$
