Whakaoti i te -4/5-0.75div11/8

$$- \frac { 4 } { 5 } - 0.75 \div 1 \frac { 1 } { 8 }$$

Aromātai

$$-\frac{22}{15}\approx -1.466666667$$

Ngā Upane Otinga

Whakawehe 0.75 ki te \frac{1\times 8+1}{8} mā te whakarea 0.75 ki te tau huripoki o \frac{1\times 8+1}{8}.

$$-\frac{4}{5}-\frac{0.75\times 8}{1\times 8+1}$$

Whakareatia te 0.75 ki te 8, ka 6.

$$-\frac{4}{5}-\frac{6}{1\times 8+1}$$

Whakareatia te 1 ki te 8, ka 8.

$$-\frac{4}{5}-\frac{6}{8+1}$$

Tāpirihia te 8 ki te 1, ka 9.

$$-\frac{4}{5}-\frac{6}{9}$$

Whakahekea te hautanga \frac{6}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{4}{5}-\frac{2}{3}$$

Ko te maha noa iti rawa atu o 5 me 3 ko 15. Me tahuri -\frac{4}{5} me \frac{2}{3} ki te hautau me te tautūnga 15.

$$-\frac{12}{15}-\frac{10}{15}$$

Tā te mea he rite te tauraro o -\frac{12}{15} me \frac{10}{15}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-12-10}{15}$$

Tangohia te 10 i te -12, ka -22.

$$-\frac{22}{15}$$

Tauwehe

$$-\frac{22}{15} = -1\frac{7}{15} = -1.4666666666666666$$
