$$1 \frac { 1 } { 2 } \times 2 \frac { 1 } { 2 }$$

Aromātai

$$\frac{15}{4}=3.75$$

Ngā Upane Otinga

Whakareatia te 1 ki te 2, ka 2.

$$\frac{2+1}{2}\times \frac{2\times 2+1}{2}$$

Tāpirihia te 2 ki te 1, ka 3.

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

Whakareatia te 2 ki te 2, ka 4.

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

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{3}{2}\times \frac{5}{2}$$

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

$$\frac{3\times 5}{2\times 2}$$

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

$$\frac{15}{4}$$

Tauwehe

$$\frac{3 \cdot 5}{2 ^ {2}} = 3\frac{3}{4} = 3.75$$
