Whakaoti i te 1/3*(3)^-1+025/frac{1{3}*(33/50-1)}=

$$\frac { \frac { 1 } { 3 } \cdot ( 3 ) ^ { - 1 } + 025 } { \frac { 1 } { 3 } \cdot ( \frac { 33 } { 50 } - 1 ) } =$$

Aromātai

$$-\frac{50}{51}\approx -0.980392157$$

Ngā Upane Otinga

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

$$\frac{\frac{1}{3}\times \frac{1}{3}+0\times 25}{\frac{1}{3}\left(\frac{33}{50}-1\right)}$$

Whakareatia te \frac{1}{3} ki te \frac{1}{3}, ka \frac{1}{9}.

$$\frac{\frac{1}{9}+0\times 25}{\frac{1}{3}\left(\frac{33}{50}-1\right)}$$

Whakareatia te 0 ki te 25, ka 0.

$$\frac{\frac{1}{9}+0}{\frac{1}{3}\left(\frac{33}{50}-1\right)}$$

Tāpirihia te \frac{1}{9} ki te 0, ka \frac{1}{9}.

$$\frac{\frac{1}{9}}{\frac{1}{3}\left(\frac{33}{50}-1\right)}$$

Tangohia te 1 i te \frac{33}{50}, ka -\frac{17}{50}.

$$\frac{\frac{1}{9}}{\frac{1}{3}\left(-\frac{17}{50}\right)}$$

Whakareatia te \frac{1}{3} ki te -\frac{17}{50}, ka -\frac{17}{150}.

$$\frac{\frac{1}{9}}{-\frac{17}{150}}$$

Whakawehe \frac{1}{9} ki te -\frac{17}{150} mā te whakarea \frac{1}{9} ki te tau huripoki o -\frac{17}{150}.

$$\frac{1}{9}\left(-\frac{150}{17}\right)$$

Whakareatia te \frac{1}{9} ki te -\frac{150}{17}, ka -\frac{50}{51}.

$$-\frac{50}{51}$$

Tauwehe

$$-\frac{50}{51} = -0.9803921568627451$$
