Distinguish percentage points from relative rate increases

Input and processing example

5% → 6%
차이 / difference: +1 퍼센트포인트 / percentage point
상대 증가 / relative increase: (6 − 5) ÷ 5 × 100 = +20%

Steps to verify

• Use matching units for both rates.
• Label the difference in points.
• Show the base for relative change.

How to interpret the result

One point is the rate difference; 20% is the increase relative to the initial rate of five. They describe different dimensions of the same change.
