Explanation:

Step1: Calculate ratio for first pair

$\frac{\text{sale price}}{\text{original price}} = \frac{12}{15} = 0.8$

Step2: Calculate ratio for second pair

$\frac{20}{25} = 0.8$

Step3: Calculate ratio for third pair

$\frac{28}{35} = 0.8$

Step4: Check constant ratio

All ratios equal 0.8 (constant)
