Ngā Upane Otinga

Whakawehe 13 ki te \frac{1\times 15+7}{15} mā te whakarea 13 ki te tau huripoki o \frac{1\times 15+7}{15}.

$$\frac{13\times 15}{1\times 15+7}\times \frac{11}{52}$$

Whakareatia te 13 ki te 15, ka 195.

$$\frac{195}{1\times 15+7}\times \frac{11}{52}$$

Whakareatia te 1 ki te 15, ka 15.

$$\frac{195}{15+7}\times \frac{11}{52}$$

Tāpirihia te 15 ki te 7, ka 22.

$$\frac{195}{22}\times \frac{11}{52}$$

Me whakarea te \frac{195}{22} ki te \frac{11}{52} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{195\times 11}{22\times 52}$$

Mahia ngā whakarea i roto i te hautanga \frac{195\times 11}{22\times 52}.

$$\frac{2145}{1144}$$

Whakahekea te hautanga \frac{2145}{1144} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 143.

$$\frac{15}{8}$$

Tauwehe

$$\frac{3 \cdot 5}{2 ^ {3}} = 1\frac{7}{8} = 1.875$$
