Whakaoti i te (3/1-frac{2{5}})(2-9/5)

$$( \frac { 3 } { 1 - \frac { 2 } { 5 } } ) ( 2 - \frac { 9 } { 5 } )$$

Aromātai

$$1$$

Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{5}{5}.

$$\frac{3}{\frac{5}{5}-\frac{2}{5}}\left(2-\frac{9}{5}\right)$$

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

$$\frac{3}{\frac{5-2}{5}}\left(2-\frac{9}{5}\right)$$

Tangohia te 2 i te 5, ka 3.

$$\frac{3}{\frac{3}{5}}\left(2-\frac{9}{5}\right)$$

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

$$3\times \frac{5}{3}\left(2-\frac{9}{5}\right)$$

Me whakakore te 3 me te 3.

$$5\left(2-\frac{9}{5}\right)$$

Me tahuri te 2 ki te hautau \frac{10}{5}.

$$5\left(\frac{10}{5}-\frac{9}{5}\right)$$

Tā te mea he rite te tauraro o \frac{10}{5} me \frac{9}{5}, me tango rāua mā te tango i ō raua taurunga.

$$5\times \frac{10-9}{5}$$

Tangohia te 9 i te 10, ka 1.

$$5\times \frac{1}{5}$$

Me whakakore te 5 me te 5.

$$1$$
