The required unknown number of percent, equal to the filled part of the square, will be denoted by the conditional variable “Y”.
Using the information of this problem, we have this proportion: 25 squares relate to 100%, as 4 squares relate to Y%.
Based on these proportions, we have the following equation: Y x 25 = 4 x 100.
The result of solving this equation will be equal to the value Y = 4 x 100/25 = 400/25 = 16%.
Answer: 16%.
