Whakaoti i te -1/12-(7/12*2/3/4/3)

$$\frac { - 1 } { 12 } - ( \frac { \frac { 7 } { 12 } \times \frac { 2 } { 3 } } { 4 / 3 } )$$

Aromātai

$$-\frac{3}{8}=-0.375$$

Ngā Upane Otinga

Ka taea te hautanga \frac{-1}{12} te tuhi anō ko -\frac{1}{12} mā te tango i te tohu tōraro.

$$-\frac{1}{12}-\frac{\frac{7}{12}\times \frac{2}{3}}{\frac{4}{3}}$$

Me whakarea te \frac{7}{12} ki te \frac{2}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$-\frac{1}{12}-\frac{\frac{7\times 2}{12\times 3}}{\frac{4}{3}}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 2}{12\times 3}.

$$-\frac{1}{12}-\frac{\frac{14}{36}}{\frac{4}{3}}$$

Whakahekea te hautanga \frac{14}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{1}{12}-\frac{\frac{7}{18}}{\frac{4}{3}}$$

Whakawehe \frac{7}{18} ki te \frac{4}{3} mā te whakarea \frac{7}{18} ki te tau huripoki o \frac{4}{3}.

$$-\frac{1}{12}-\frac{7}{18}\times \frac{3}{4}$$

Me whakarea te \frac{7}{18} ki te \frac{3}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$-\frac{1}{12}-\frac{7\times 3}{18\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 3}{18\times 4}.

$$-\frac{1}{12}-\frac{21}{72}$$

Whakahekea te hautanga \frac{21}{72} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{1}{12}-\frac{7}{24}$$

Ko te maha noa iti rawa atu o 12 me 24 ko 24. Me tahuri -\frac{1}{12} me \frac{7}{24} ki te hautau me te tautūnga 24.

$$-\frac{2}{24}-\frac{7}{24}$$

Tā te mea he rite te tauraro o -\frac{2}{24} me \frac{7}{24}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-2-7}{24}$$

Tangohia te 7 i te -2, ka -9.

$$\frac{-9}{24}$$

Whakahekea te hautanga \frac{-9}{24} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

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

Tauwehe

$$-\frac{3}{8} = -0.375$$
