Whakaoti i te 3/4+1/2*(3/4-1)=

$$\frac { 3 } { 4 } + \frac { 1 } { 2 } \cdot ( \frac { 3 } { 4 } - 1 ) =$$

Aromātai

$$\frac{5}{8}=0.625$$

Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{4}{4}.

$$\frac{3}{4}+\frac{1}{2}\left(\frac{3}{4}-\frac{4}{4}\right)$$

Tā te mea he rite te tauraro o \frac{3}{4} me \frac{4}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3}{4}+\frac{1}{2}\times \frac{3-4}{4}$$

Tangohia te 4 i te 3, ka -1.

$$\frac{3}{4}+\frac{1}{2}\left(-\frac{1}{4}\right)$$

Me whakarea te \frac{1}{2} ki te -\frac{1}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3}{4}+\frac{1\left(-1\right)}{2\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\left(-1\right)}{2\times 4}.

$$\frac{3}{4}+\frac{-1}{8}$$

Ka taea te hautanga \frac{-1}{8} te tuhi anō ko -\frac{1}{8} mā te tango i te tohu tōraro.

$$\frac{3}{4}-\frac{1}{8}$$

Ko te maha noa iti rawa atu o 4 me 8 ko 8. Me tahuri \frac{3}{4} me \frac{1}{8} ki te hautau me te tautūnga 8.

$$\frac{6}{8}-\frac{1}{8}$$

Tā te mea he rite te tauraro o \frac{6}{8} me \frac{1}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{6-1}{8}$$

Tangohia te 1 i te 6, ka 5.

$$\frac{5}{8}$$

Tauwehe

$$\frac{5}{2 ^ {3}} = 0.625$$
