Whakaoti i te 41/6*1/3-1/2*4/9=

$$4 \frac { 1 } { 6 } \cdot \frac { 1 } { 3 } - \frac { 1 } { 2 } \cdot \frac { 4 } { 9 } =$$

Aromātai

$$\frac{7}{6}\approx 1.166666667$$

Ngā Upane Otinga

Whakareatia te 4 ki te 6, ka 24.

$$\frac{24+1}{6}\times \frac{1}{3}-\frac{1}{2}\times \frac{4}{9}$$

Tāpirihia te 24 ki te 1, ka 25.

$$\frac{25}{6}\times \frac{1}{3}-\frac{1}{2}\times \frac{4}{9}$$

Me whakarea te \frac{25}{6} ki te \frac{1}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25\times 1}{6\times 3}-\frac{1}{2}\times \frac{4}{9}$$

Mahia ngā whakarea i roto i te hautanga \frac{25\times 1}{6\times 3}.

$$\frac{25}{18}-\frac{1}{2}\times \frac{4}{9}$$

Me whakarea te \frac{1}{2} ki te \frac{4}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25}{18}-\frac{1\times 4}{2\times 9}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 4}{2\times 9}.

$$\frac{25}{18}-\frac{4}{18}$$

Tā te mea he rite te tauraro o \frac{25}{18} me \frac{4}{18}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{25-4}{18}$$

Tangohia te 4 i te 25, ka 21.

$$\frac{21}{18}$$

Whakahekea te hautanga \frac{21}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{7}{6}$$

Tauwehe

$$\frac{7}{2 \cdot 3} = 1\frac{1}{6} = 1.1666666666666667$$
