Whakaoti i te 31/8-3/2*1/4=

$$3 \frac { 1 } { 8 } - \frac { 3 } { 2 } \cdot \frac { 1 } { 4 } =$$

Aromātai

$$\frac{11}{4}=2.75$$

Ngā Upane Otinga

Whakareatia te 3 ki te 8, ka 24.

$$\frac{24+1}{8}-\frac{3}{2}\times \frac{1}{4}$$

Tāpirihia te 24 ki te 1, ka 25.

$$\frac{25}{8}-\frac{3}{2}\times \frac{1}{4}$$

Me whakarea te \frac{3}{2} ki te \frac{1}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{25}{8}-\frac{3\times 1}{2\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 1}{2\times 4}.

$$\frac{25}{8}-\frac{3}{8}$$

Tā te mea he rite te tauraro o \frac{25}{8} me \frac{3}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{25-3}{8}$$

Tangohia te 3 i te 25, ka 22.

$$\frac{22}{8}$$

Whakahekea te hautanga \frac{22}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{11}{4}$$

Tauwehe

$$\frac{11}{2 ^ {2}} = 2\frac{3}{4} = 2.75$$
