Tangohia te 4.5 i te -7.5, ka -12.

$$-12+15\times \frac{-32.25}{3}$$

Whakarohaina te \frac{-32.25}{3} mā te whakarea i te taurunga me te tauraro ki te 100.

$$-12+15\times \frac{-3225}{300}$$

Whakahekea te hautanga \frac{-3225}{300} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 75.

$$-12+15\left(-\frac{43}{4}\right)$$

Tuhia te 15\left(-\frac{43}{4}\right) hei hautanga kotahi.

$$-12+\frac{15\left(-43\right)}{4}$$

Whakareatia te 15 ki te -43, ka -645.

$$-12+\frac{-645}{4}$$

Ka taea te hautanga \frac{-645}{4} te tuhi anō ko -\frac{645}{4} mā te tango i te tohu tōraro.

$$-12-\frac{645}{4}$$

Me tahuri te -12 ki te hautau -\frac{48}{4}.

$$-\frac{48}{4}-\frac{645}{4}$$

Tā te mea he rite te tauraro o -\frac{48}{4} me \frac{645}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-48-645}{4}$$

Tangohia te 645 i te -48, ka -693.

$$-\frac{693}{4}$$
