Whakaoti i te 2^-1-3^-1/2^-1+3^-1

$$\frac { 2 ^ { - 1 } - 3 ^ { - 1 } } { 2 ^ { - 1 } + 3 ^ { - 1 } }$$

Aromātai

$$\frac{1}{5}=0.2$$

Ngā Upane Otinga

Tātaihia te 2 mā te pū o -1, kia riro ko \frac{1}{2}.

$$\frac{\frac{1}{2}-3^{-1}}{2^{-1}+3^{-1}}$$

Tātaihia te 3 mā te pū o -1, kia riro ko \frac{1}{3}.

$$\frac{\frac{1}{2}-\frac{1}{3}}{2^{-1}+3^{-1}}$$

Tangohia te \frac{1}{3} i te \frac{1}{2}, ka \frac{1}{6}.

$$\frac{\frac{1}{6}}{2^{-1}+3^{-1}}$$

Tātaihia te 2 mā te pū o -1, kia riro ko \frac{1}{2}.

$$\frac{\frac{1}{6}}{\frac{1}{2}+3^{-1}}$$

Tātaihia te 3 mā te pū o -1, kia riro ko \frac{1}{3}.

$$\frac{\frac{1}{6}}{\frac{1}{2}+\frac{1}{3}}$$

Tāpirihia te \frac{1}{2} ki te \frac{1}{3}, ka \frac{5}{6}.

$$\frac{\frac{1}{6}}{\frac{5}{6}}$$

Whakawehe \frac{1}{6} ki te \frac{5}{6} mā te whakarea \frac{1}{6} ki te tau huripoki o \frac{5}{6}.

$$\frac{1}{6}\times \frac{6}{5}$$

Whakareatia te \frac{1}{6} ki te \frac{6}{5}, ka \frac{1}{5}.

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

Tauwehe

$$\frac{1}{5} = 0.2$$
