Whakaoti i te (2-1/4)*(3-1/2)]-sqrt{1/9}

$$( 2 - \frac { 1 } { 4 } ) \cdot ( 3 - \frac { 1 } { 2 } ) ] - \sqrt { \frac { 1 } { 9 } }$$

Aromātai

$$\frac{35}{8}=4.375$$

Ngā Upane Otinga

Me tahuri te 2 ki te hautau \frac{8}{4}.

$$\left(\frac{8}{4}-\frac{1}{4}\right)\left(3-\frac{1}{2}\right)$$

Tā te mea he rite te tauraro o \frac{8}{4} me \frac{1}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{8-1}{4}\left(3-\frac{1}{2}\right)$$

Tangohia te 1 i te 8, ka 7.

$$\frac{7}{4}\left(3-\frac{1}{2}\right)$$

Me tahuri te 3 ki te hautau \frac{6}{2}.

$$\frac{7}{4}\left(\frac{6}{2}-\frac{1}{2}\right)$$

Tā te mea he rite te tauraro o \frac{6}{2} me \frac{1}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{7}{4}\times \frac{6-1}{2}$$

Tangohia te 1 i te 6, ka 5.

$$\frac{7}{4}\times \frac{5}{2}$$

Me whakarea te \frac{7}{4} ki te \frac{5}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7\times 5}{4\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 5}{4\times 2}.

$$\frac{35}{8}$$

Tauwehe

$$\frac{5 \cdot 7}{2 ^ {3}} = 4\frac{3}{8} = 4.375$$
