Whakaoti i te -3/-8--3/4=

$$\frac { - 3 } { - 8 } - \frac { - 3 } { 4 } =$$

Aromātai

$$\frac{9}{8}=1.125$$

Ngā Upane Otinga

Ka taea te hautanga \frac{-3}{-8} te whakamāmā ki te \frac{3}{8} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$\frac{3}{8}-\frac{-3}{4}$$

Ka taea te hautanga \frac{-3}{4} te tuhi anō ko -\frac{3}{4} mā te tango i te tohu tōraro.

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

Ko te tauaro o -\frac{3}{4} ko \frac{3}{4}.

$$\frac{3}{8}+\frac{3}{4}$$

Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri \frac{3}{8} me \frac{3}{4} ki te hautau me te tautūnga 8.

$$\frac{3}{8}+\frac{6}{8}$$

Tā te mea he rite te tauraro o \frac{3}{8} me \frac{6}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+6}{8}$$

Tāpirihia te 3 ki te 6, ka 9.

$$\frac{9}{8}$$

Tauwehe

$$\frac{3 ^ {2}}{2 ^ {3}} = 1\frac{1}{8} = 1.125$$
