Whakaoti i te 7/12div3/4+5/12*4/3

$$\frac { 7 } { 12 } \div \frac { 3 } { 4 } + \frac { 5 } { 12 } \times \frac { 4 } { 3 }$$

Aromātai

$$\frac{4}{3}\approx 1.333333333$$

Ngā Upane Otinga

Whakawehe \frac{7}{12} ki te \frac{3}{4} mā te whakarea \frac{7}{12} ki te tau huripoki o \frac{3}{4}.

$$\frac{7}{12}\times \frac{4}{3}+\frac{5}{12}\times \frac{4}{3}$$

Me whakarea te \frac{7}{12} ki te \frac{4}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7\times 4}{12\times 3}+\frac{5}{12}\times \frac{4}{3}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 4}{12\times 3}.

$$\frac{28}{36}+\frac{5}{12}\times \frac{4}{3}$$

Whakahekea te hautanga \frac{28}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{7}{9}+\frac{5}{12}\times \frac{4}{3}$$

Me whakarea te \frac{5}{12} ki te \frac{4}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7}{9}+\frac{5\times 4}{12\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{5\times 4}{12\times 3}.

$$\frac{7}{9}+\frac{20}{36}$$

Whakahekea te hautanga \frac{20}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{7}{9}+\frac{5}{9}$$

Tā te mea he rite te tauraro o \frac{7}{9} me \frac{5}{9}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{7+5}{9}$$

Tāpirihia te 7 ki te 5, ka 12.

$$\frac{12}{9}$$

Whakahekea te hautanga \frac{12}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{4}{3}$$

Tauwehe

$$\frac{2 ^ {2}}{3} = 1\frac{1}{3} = 1.3333333333333333$$
