Whakaoti i te 3/4*2/5+1/4div5/2

$$\frac { 3 } { 4 } \times \frac { 2 } { 5 } + \frac { 1 } { 4 } \div \frac { 5 } { 2 }$$

Aromātai

$$\frac{2}{5}=0.4$$

Ngā Upane Otinga

Me whakarea te \frac{3}{4} ki te \frac{2}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3\times 2}{4\times 5}+\frac{\frac{1}{4}}{\frac{5}{2}}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 2}{4\times 5}.

$$\frac{6}{20}+\frac{\frac{1}{4}}{\frac{5}{2}}$$

Whakahekea te hautanga \frac{6}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{3}{10}+\frac{\frac{1}{4}}{\frac{5}{2}}$$

Whakawehe \frac{1}{4} ki te \frac{5}{2} mā te whakarea \frac{1}{4} ki te tau huripoki o \frac{5}{2}.

$$\frac{3}{10}+\frac{1}{4}\times \frac{2}{5}$$

Me whakarea te \frac{1}{4} ki te \frac{2}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3}{10}+\frac{1\times 2}{4\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 2}{4\times 5}.

$$\frac{3}{10}+\frac{2}{20}$$

Whakahekea te hautanga \frac{2}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{3}{10}+\frac{1}{10}$$

Tā te mea he rite te tauraro o \frac{3}{10} me \frac{1}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+1}{10}$$

Tāpirihia te 3 ki te 1, ka 4.

$$\frac{4}{10}$$

Whakahekea te hautanga \frac{4}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{2}{5}$$

Tauwehe

$$\frac{2}{5} = 0.4$$
