$$\frac{\frac{3740}{15}\times 8\left(4-8\right)}{1683-\left(4-8\right)}$$

Whakahekea te hautanga \frac{3740}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{\frac{748}{3}\times 8\left(4-8\right)}{1683-\left(4-8\right)}$$

Tuhia te \frac{748}{3}\times 8 hei hautanga kotahi.

$$\frac{\frac{748\times 8}{3}\left(4-8\right)}{1683-\left(4-8\right)}$$

Whakareatia te 748 ki te 8, ka 5984.

$$\frac{\frac{5984}{3}\left(4-8\right)}{1683-\left(4-8\right)}$$

Tangohia te 8 i te 4, ka -4.

$$\frac{\frac{5984}{3}\left(-4\right)}{1683-\left(4-8\right)}$$

Tuhia te \frac{5984}{3}\left(-4\right) hei hautanga kotahi.

$$\frac{\frac{5984\left(-4\right)}{3}}{1683-\left(4-8\right)}$$

Whakareatia te 5984 ki te -4, ka -23936.

$$\frac{\frac{-23936}{3}}{1683-\left(4-8\right)}$$

Ka taea te hautanga \frac{-23936}{3} te tuhi anō ko -\frac{23936}{3} mā te tango i te tohu tōraro.

$$\frac{-\frac{23936}{3}}{1683-\left(4-8\right)}$$

Tangohia te 8 i te 4, ka -4.

$$\frac{-\frac{23936}{3}}{1683-\left(-4\right)}$$

Ko te tauaro o -4 ko 4.

$$\frac{-\frac{23936}{3}}{1683+4}$$

Tāpirihia te 1683 ki te 4, ka 1687.

$$\frac{-\frac{23936}{3}}{1687}$$

Tuhia te \frac{-\frac{23936}{3}}{1687} hei hautanga kotahi.

$$\frac{-23936}{3\times 1687}$$

Whakareatia te 3 ki te 1687, ka 5061.

$$\frac{-23936}{5061}$$

Ka taea te hautanga \frac{-23936}{5061} te tuhi anō ko -\frac{23936}{5061} mā te tango i te tohu tōraro.

$$-\frac{23936}{5061}$$

Tauwehe

$$-\frac{23936}{5061} = -4\frac{3692}{5061} = -4.729500098794705$$
