$$\frac { \frac { 3 } { 4 } \times 25 } { \frac { 1 } { 2 } }$$

Aromātai

$$\frac{75}{2}=37.5$$

Ngā Upane Otinga

Tuhia te \frac{3}{4}\times 25 hei hautanga kotahi.

$$\frac{\frac{3\times 25}{4}}{\frac{1}{2}}$$

Whakareatia te 3 ki te 25, ka 75.

$$\frac{\frac{75}{4}}{\frac{1}{2}}$$

Whakawehe \frac{75}{4} ki te \frac{1}{2} mā te whakarea \frac{75}{4} ki te tau huripoki o \frac{1}{2}.

$$\frac{75}{4}\times 2$$

Tuhia te \frac{75}{4}\times 2 hei hautanga kotahi.

$$\frac{75\times 2}{4}$$

Whakareatia te 75 ki te 2, ka 150.

$$\frac{150}{4}$$

Whakahekea te hautanga \frac{150}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{75}{2}$$

Tauwehe

$$\frac{3 \cdot 5 ^ {2}}{2} = 37\frac{1}{2} = 37.5$$
