Whakaoti i te 6*2/3-85/8

$$6 \cdot \frac { 2 } { 3 } - 8 \frac { 5 } { 8 }$$

Aromātai

$$-\frac{37}{8}=-4.625$$

Ngā Upane Otinga

Tuhia te 6\times \frac{2}{3} hei hautanga kotahi.

$$\frac{6\times 2}{3}-\frac{8\times 8+5}{8}$$

Whakareatia te 6 ki te 2, ka 12.

$$\frac{12}{3}-\frac{8\times 8+5}{8}$$

Whakawehea te 12 ki te 3, kia riro ko 4.

$$4-\frac{8\times 8+5}{8}$$

Whakareatia te 8 ki te 8, ka 64.

$$4-\frac{64+5}{8}$$

Tāpirihia te 64 ki te 5, ka 69.

$$4-\frac{69}{8}$$

Me tahuri te 4 ki te hautau \frac{32}{8}.

$$\frac{32}{8}-\frac{69}{8}$$

Tā te mea he rite te tauraro o \frac{32}{8} me \frac{69}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{32-69}{8}$$

Tangohia te 69 i te 32, ka -37.

$$-\frac{37}{8}$$

Tauwehe

$$-\frac{37}{8} = -4\frac{5}{8} = -4.625$$
