subtract old from new you get 5.3
divide that by old
5.3/6.2=0.8548
multiply by 100
85.48%

Beginning = 6.2 cm
Now = 11.5 cm
How much it grows ?
Now - Beginning ===> 11.5 cm - 6.2 cm = 5.3 cm
What is 5.3 cm compare to the beginning?
5.3 cm over 6.2 cm OR
5.3 cm / 6.2 cm = .85 x 100 = 85%
It means it grows 85%

Increase = 5.3 cm
% increase = (5.3 / 6.2) x 100%
% increase = 86% (to nearest whole number)

(11.5 - 6.2)/6.2 ~= 0.85 = (0.85)(100/100) = 85/100 = 85%.
