☄\underline{ \underline{ \text{Solution}}} :

✏ Let , the number of antique houses in a village be ' x ' .

⤑\sf{ \frac{12}{x}  =  \frac{4}{5}}

Apply cross product property

⤑\sf{4 \times x = 12 \times 5}

⤑\sf{4x = 60}

⤑\sf{ \frac{4x}{4}  =  \frac{60}{4}}

⤑\sf{x = 15}

So, The number of antique houses in a village is 15.
