Whakaoti i te 101/2div31/8

$$10 \frac { 1 } { 2 } \div 3 \frac { 1 } { 8 }$$

Aromātai

$$\frac{84}{25}=3.36$$

Ngā Upane Otinga

Whakawehe \frac{10\times 2+1}{2} ki te \frac{3\times 8+1}{8} mā te whakarea \frac{10\times 2+1}{2} ki te tau huripoki o \frac{3\times 8+1}{8}.

$$\frac{\left(10\times 2+1\right)\times 8}{2\left(3\times 8+1\right)}$$

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

$$\frac{4\left(1+2\times 10\right)}{1+3\times 8}$$

Whakareatia te 2 ki te 10, ka 20.

$$\frac{4\left(1+20\right)}{1+3\times 8}$$

Tāpirihia te 1 ki te 20, ka 21.

$$\frac{4\times 21}{1+3\times 8}$$

Whakareatia te 4 ki te 21, ka 84.

$$\frac{84}{1+3\times 8}$$

Whakareatia te 3 ki te 8, ka 24.

$$\frac{84}{1+24}$$

Tāpirihia te 1 ki te 24, ka 25.

$$\frac{84}{25}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 3 \cdot 7}{5 ^ {2}} = 3\frac{9}{25} = 3.36$$
