Whakaoti i te 4-2/5/frac{5{9}-2/6}=

$$\frac { 4 - \frac { 2 } { 5 } } { \frac { 5 } { 9 } - \frac { 2 } { 6 } } =$$

Aromātai

$$\frac{81}{5}=16.2$$

Ngā Upane Otinga

Me tahuri te 4 ki te hautau \frac{20}{5}.

$$\frac{\frac{20}{5}-\frac{2}{5}}{\frac{5}{9}-\frac{2}{6}}$$

Tā te mea he rite te tauraro o \frac{20}{5} me \frac{2}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{20-2}{5}}{\frac{5}{9}-\frac{2}{6}}$$

Tangohia te 2 i te 20, ka 18.

$$\frac{\frac{18}{5}}{\frac{5}{9}-\frac{2}{6}}$$

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

$$\frac{\frac{18}{5}}{\frac{5}{9}-\frac{1}{3}}$$

Ko te maha noa iti rawa atu o 9 me 3 ko 9. Me tahuri \frac{5}{9} me \frac{1}{3} ki te hautau me te tautūnga 9.

$$\frac{\frac{18}{5}}{\frac{5}{9}-\frac{3}{9}}$$

Tā te mea he rite te tauraro o \frac{5}{9} me \frac{3}{9}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{18}{5}}{\frac{5-3}{9}}$$

Tangohia te 3 i te 5, ka 2.

$$\frac{\frac{18}{5}}{\frac{2}{9}}$$

Whakawehe \frac{18}{5} ki te \frac{2}{9} mā te whakarea \frac{18}{5} ki te tau huripoki o \frac{2}{9}.

$$\frac{18}{5}\times \frac{9}{2}$$

Me whakarea te \frac{18}{5} ki te \frac{9}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{18\times 9}{5\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{18\times 9}{5\times 2}.

$$\frac{162}{10}$$

Whakahekea te hautanga \frac{162}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{81}{5}$$

Tauwehe

$$\frac{3 ^ {4}}{5} = 16\frac{1}{5} = 16.2$$
