Solar power's share of a site's energy rises from 12.5% to 15%. What is the rise in percentage points? Enter the number of percentage points.
Respuesta correcta
2.5
Explicación
The point increase is the direct difference 15 - 12.5 = 2.5 percentage points. Calculating 2.5 / 12.5 × 100 = 20 would answer a relative-percent question instead.
