This is a particularly simple case: increasing by 3% is multiplying by 1.03 (1 + 3/100) not by 1.3 increasing by 137% is multiplying by 2.37 (1 + 137/100) not by 1.137 increasing by 1000% is multiplying by 11 (1 + 1000/100) not by 1.1000 or 10 or 1000 decreasing by 1% is multiplying by 0.99 (1  1/100) not dividing by 1.01 decreasing by 45% is multiplying by 0.55 (1  45/100) not dividing by 1.45 Good Hunting!
