Kam tas paredzēts
Anyone checking a discount, a grade or a change between two values.
Kā darbojas aprēķins
X% of Y = X/100 × Y. ‘X is what % of Y’ = X/Y × 100. Change = (new − old) / old × 100.
Formula
part = p/100 × whole; percent = part/whole × 100; change = (new − old)/old × 100
Pieņēmumi

- Change uses the first value as the base.
Ierobežojumi
