To give: two examples that are given proportional.

Explanation of Solution
Given information:
The given proportion
Calculation:
The two ratios are said to be in proportion if they are equal.
Consider the below ratios.
Compare the ratios
Divide the numerator and denominator by 2.
Divide the numerator and denominator by 4.
Since the three ratios
Therefore, the ratios
Hence, the required examples are
