Whakaoti i te [(1-1/3)^2+(1-1/9)]:(2-1/3)=

$$[ ( 1 - \frac { 1 } { 3 } ) ^ { 2 } + ( 1 - \frac { 1 } { 9 } ) ] : ( 2 - \frac { 1 } { 3 } ) =$$

Aromātai

$$\frac{4}{5}=0.8$$

Ngā Upane Otinga

Tangohia te \frac{1}{3} i te 1, ka \frac{2}{3}.

$$\frac{\left(\frac{2}{3}\right)^{2}+1-\frac{1}{9}}{2-\frac{1}{3}}$$

Tātaihia te \frac{2}{3} mā te pū o 2, kia riro ko \frac{4}{9}.

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

Tāpirihia te \frac{4}{9} ki te 1, ka \frac{13}{9}.

$$\frac{\frac{13}{9}-\frac{1}{9}}{2-\frac{1}{3}}$$

Tangohia te \frac{1}{9} i te \frac{13}{9}, ka \frac{4}{3}.

$$\frac{\frac{4}{3}}{2-\frac{1}{3}}$$

Tangohia te \frac{1}{3} i te 2, ka \frac{5}{3}.

$$\frac{\frac{4}{3}}{\frac{5}{3}}$$

Whakawehe \frac{4}{3} ki te \frac{5}{3} mā te whakarea \frac{4}{3} ki te tau huripoki o \frac{5}{3}.

$$\frac{4}{3}\times \frac{3}{5}$$

Whakareatia te \frac{4}{3} ki te \frac{3}{5}, ka \frac{4}{5}.

$$\frac{4}{5}$$

Tauwehe

$$\frac{2 ^ {2}}{5} = 0.8$$
