Me whakarea te -\frac{1}{12} ki te \frac{1}{16} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-1}{12\times 16}+\frac{1}{8}\times \frac{1}{4}$$

Mahia ngā whakarea i roto i te hautanga \frac{-1}{12\times 16}.

$$\frac{-1}{192}+\frac{1}{8}\times \frac{1}{4}$$

Ka taea te hautanga \frac{-1}{192} te tuhi anō ko -\frac{1}{192} mā te tango i te tohu tōraro.

$$-\frac{1}{192}+\frac{1}{8}\times \frac{1}{4}$$

Me whakarea te \frac{1}{8} ki te \frac{1}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$-\frac{1}{192}+\frac{1\times 1}{8\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 1}{8\times 4}.

$$-\frac{1}{192}+\frac{1}{32}$$

Ko te maha noa iti rawa atu o 192 me 32 ko 192. Me tahuri -\frac{1}{192} me \frac{1}{32} ki te hautau me te tautūnga 192.

$$-\frac{1}{192}+\frac{6}{192}$$

Tā te mea he rite te tauraro o -\frac{1}{192} me \frac{6}{192}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-1+6}{192}$$

Tāpirihia te -1 ki te 6, ka 5.

$$\frac{5}{192}$$

Tauwehe

$$\frac{5}{2 ^ {6} \cdot 3} = 0.026041666666666668$$
