Whakaoti i te 1/4/frac{2{4}}-2+3/4/4

$$\frac { \frac { 1 } { 4 } } { \frac { 2 } { 4 } } - 2 + \frac { \frac { 3 } { 4 } } { 4 }$$

Aromātai

$$-\frac{21}{16}=-1.3125$$

Ngā Upane Otinga

Whakawehe \frac{1}{4} ki te \frac{2}{4} mā te whakarea \frac{1}{4} ki te tau huripoki o \frac{2}{4}.

$$\frac{4}{4\times 2}-2+\frac{\frac{3}{4}}{4}$$

Whakareatia te 4 ki te 2, ka 8.

$$\frac{4}{8}-2+\frac{\frac{3}{4}}{4}$$

Whakahekea te hautanga \frac{4}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{1}{2}-2+\frac{\frac{3}{4}}{4}$$

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

$$\frac{1}{2}-\frac{4}{2}+\frac{\frac{3}{4}}{4}$$

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{4}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1-4}{2}+\frac{\frac{3}{4}}{4}$$

Tangohia te 4 i te 1, ka -3.

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

Tuhia te \frac{\frac{3}{4}}{4} hei hautanga kotahi.

$$-\frac{3}{2}+\frac{3}{4\times 4}$$

Whakareatia te 4 ki te 4, ka 16.

$$-\frac{3}{2}+\frac{3}{16}$$

Ko te maha noa iti rawa atu o 2 me 16 ko 16. Me tahuri -\frac{3}{2} me \frac{3}{16} ki te hautau me te tautūnga 16.

$$-\frac{24}{16}+\frac{3}{16}$$

Tā te mea he rite te tauraro o -\frac{24}{16} me \frac{3}{16}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-24+3}{16}$$

Tāpirihia te -24 ki te 3, ka -21.

$$-\frac{21}{16}$$

Tauwehe

$$-\frac{21}{16} = -1\frac{5}{16} = -1.3125$$
