Whakaoti i te 3/8div11/2+11/4

$$\frac{ 3 }{ 8 } \div 1 \frac{ 1 }{ 2 } +1 \frac{ 1 }{ 4 }$$

Aromātai

$$\frac{3}{2}=1.5$$

Ngā Upane Otinga

Whakawehe \frac{3}{8} ki te \frac{1\times 2+1}{2} mā te whakarea \frac{3}{8} ki te tau huripoki o \frac{1\times 2+1}{2}.

$$\frac{3\times 2}{8\left(1\times 2+1\right)}+\frac{1\times 4+1}{4}$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{3}{4\left(1+2\right)}+\frac{1\times 4+1}{4}$$

Tāpirihia te 1 ki te 2, ka 3.

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

Whakareatia te 4 ki te 3, ka 12.

$$\frac{3}{12}+\frac{1\times 4+1}{4}$$

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

$$\frac{1}{4}+\frac{1\times 4+1}{4}$$

Whakareatia te 1 ki te 4, ka 4.

$$\frac{1}{4}+\frac{4+1}{4}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{1}{4}+\frac{5}{4}$$

Tā te mea he rite te tauraro o \frac{1}{4} me \frac{5}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1+5}{4}$$

Tāpirihia te 1 ki te 5, ka 6.

$$\frac{6}{4}$$

Whakahekea te hautanga \frac{6}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{3}{2}$$

Tauwehe

$$\frac{3}{2} = 1\frac{1}{2} = 1.5$$
