Ngā Upane Otinga

Whakawehe -\frac{10}{81} ki te \frac{1}{9} mā te whakarea -\frac{10}{81} ki te tau huripoki o \frac{1}{9}.

$$-\frac{10}{81}\times 9\left(-\frac{5}{9}\right)$$

Tuhia te -\frac{10}{81}\times 9 hei hautanga kotahi.

$$\frac{-10\times 9}{81}\left(-\frac{5}{9}\right)$$

Whakareatia te -10 ki te 9, ka -90.

$$\frac{-90}{81}\left(-\frac{5}{9}\right)$$

Whakahekea te hautanga \frac{-90}{81} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

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

Me whakarea te -\frac{10}{9} ki te -\frac{5}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

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

Mahia ngā whakarea i roto i te hautanga \frac{-10\left(-5\right)}{9\times 9}.

$$\frac{50}{81}$$

Tauwehe
