Given that x percent of 80 equals 20 percent of y, what are the values of x and y?

Explanation

From the equation x% of 80 = 20% of y, we have (x/100) × 80 = (20/100) × y, which simplifies to 4x = y. This means y depends on x, so there are infinitely many pairs (x, y) satisfying the equation. Therefore, exact values of x and y cannot be determined.
