Ngā Upane Otinga

Whakawehe \frac{\frac{11}{15}}{-\frac{2\times 5+3}{5}} ki te \frac{9}{13} mā te whakarea \frac{\frac{11}{15}}{-\frac{2\times 5+3}{5}} ki te tau huripoki o \frac{9}{13}.

$$\frac{\frac{11}{15}\times 13}{\left(-\frac{2\times 5+3}{5}\right)\times 9}$$

Tuhia te \frac{11}{15}\times 13 hei hautanga kotahi.

$$\frac{\frac{11\times 13}{15}}{\left(-\frac{2\times 5+3}{5}\right)\times 9}$$

Whakareatia te 11 ki te 13, ka 143.

$$\frac{\frac{143}{15}}{\left(-\frac{2\times 5+3}{5}\right)\times 9}$$

Whakareatia te 2 ki te 5, ka 10.

$$\frac{\frac{143}{15}}{\left(-\frac{10+3}{5}\right)\times 9}$$

Tāpirihia te 10 ki te 3, ka 13.

$$\frac{\frac{143}{15}}{-\frac{13}{5}\times 9}$$

Tuhia te -\frac{13}{5}\times 9 hei hautanga kotahi.

$$\frac{\frac{143}{15}}{\frac{-13\times 9}{5}}$$

Whakareatia te -13 ki te 9, ka -117.

$$\frac{\frac{143}{15}}{\frac{-117}{5}}$$

Ka taea te hautanga \frac{-117}{5} te tuhi anō ko -\frac{117}{5} mā te tango i te tohu tōraro.

$$\frac{\frac{143}{15}}{-\frac{117}{5}}$$

Whakawehe \frac{143}{15} ki te -\frac{117}{5} mā te whakarea \frac{143}{15} ki te tau huripoki o -\frac{117}{5}.

$$\frac{143}{15}\left(-\frac{5}{117}\right)$$

Me whakarea te \frac{143}{15} ki te -\frac{5}{117} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{143\left(-5\right)}{15\times 117}$$

Mahia ngā whakarea i roto i te hautanga \frac{143\left(-5\right)}{15\times 117}.

$$\frac{-715}{1755}$$

Whakahekea te hautanga \frac{-715}{1755} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 65.

$$-\frac{11}{27}$$
