Aromātai

$$-\frac{13}{8}=-1.625$$

Ngā Upane Otinga

Whakareatia te 2 ki te 6, ka 12.

$$\frac{-\frac{12+1}{6}}{\frac{4}{3}}$$

Tāpirihia te 12 ki te 1, ka 13.

$$\frac{-\frac{13}{6}}{\frac{4}{3}}$$

Whakawehe -\frac{13}{6} ki te \frac{4}{3} mā te whakarea -\frac{13}{6} ki te tau huripoki o \frac{4}{3}.

$$-\frac{13}{6}\times \frac{3}{4}$$

Me whakarea te -\frac{13}{6} ki te \frac{3}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-13\times 3}{6\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{-13\times 3}{6\times 4}.

$$\frac{-39}{24}$$

Whakahekea te hautanga \frac{-39}{24} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{13}{8}$$

Tauwehe

$$-\frac{13}{8} = -1\frac{5}{8} = -1.625$$
