Whakaoti i te 11/2*1.6div14/5

$$1 \frac { 1 } { 2 } \times 1.6 \div 1 \frac { 4 } { 5 }$$

Aromātai

$$\frac{4}{3}\approx 1.333333333$$

Ngā Upane Otinga

Whakareatia te 1 ki te 2, ka 2.

$$\frac{\frac{2+1}{2}\times 1.6}{\frac{1\times 5+4}{5}}$$

Tāpirihia te 2 ki te 1, ka 3.

$$\frac{\frac{3}{2}\times 1.6}{\frac{1\times 5+4}{5}}$$

Me tahuri ki tau ā-ira 1.6 ki te hautau \frac{16}{10}. Whakahekea te hautanga \frac{16}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{\frac{3}{2}\times \frac{8}{5}}{\frac{1\times 5+4}{5}}$$

Me whakarea te \frac{3}{2} ki te \frac{8}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\frac{3\times 8}{2\times 5}}{\frac{1\times 5+4}{5}}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 8}{2\times 5}.

$$\frac{\frac{24}{10}}{\frac{1\times 5+4}{5}}$$

Whakahekea te hautanga \frac{24}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{\frac{12}{5}}{\frac{1\times 5+4}{5}}$$

Whakareatia te 1 ki te 5, ka 5.

$$\frac{\frac{12}{5}}{\frac{5+4}{5}}$$

Tāpirihia te 5 ki te 4, ka 9.

$$\frac{\frac{12}{5}}{\frac{9}{5}}$$

Whakawehe \frac{12}{5} ki te \frac{9}{5} mā te whakarea \frac{12}{5} ki te tau huripoki o \frac{9}{5}.

$$\frac{12}{5}\times \frac{5}{9}$$

Me whakarea te \frac{12}{5} ki te \frac{5}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{12\times 5}{5\times 9}$$

Me whakakore tahi te 5 i te taurunga me te tauraro.

$$\frac{12}{9}$$

Whakahekea te hautanga \frac{12}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{4}{3}$$

Tauwehe

$$\frac{2 ^ {2}}{3} = 1\frac{1}{3} = 1.3333333333333333$$
