Whakaoti i te -3/5*{1-(2/3)^2}=

$$- \frac { 3 } { 5 } \times \{ 1 - ( \frac { 2 } { 3 } ) ^ { 2 } \} =$$

Aromātai

$$-\frac{1}{3}\approx -0.333333333$$

Ngā Upane Otinga

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

$$-\frac{3}{5}\left(1-\frac{4}{9}\right)$$

Me tahuri te 1 ki te hautau \frac{9}{9}.

$$-\frac{3}{5}\left(\frac{9}{9}-\frac{4}{9}\right)$$

Tā te mea he rite te tauraro o \frac{9}{9} me \frac{4}{9}, me tango rāua mā te tango i ō raua taurunga.

$$-\frac{3}{5}\times \frac{9-4}{9}$$

Tangohia te 4 i te 9, ka 5.

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

Me whakarea te -\frac{3}{5} ki te \frac{5}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

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

Me whakakore tahi te 5 i te taurunga me te tauraro.

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

Whakahekea te hautanga \frac{-3}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

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

Tauwehe

$$-\frac{1}{3} = -0.3333333333333333$$
