If you would like to know which of the girls will have the greatest percent of change in height, you can calculate this using the following steps:

x% of 60 inches is 63 inches
x% * 60 = 63
x/100 * 60 = 63
x = 63 * 100 / 60 = 105% ... 5%

y% * 62 = 65
y/100 * 62 = 65
y = 65 * 100 / 62 = 104.84% ... 4.84%

w% * 64 = 67
w/100 * 64 = 67
w = 67 * 100 / 64 = 104.69% ... 4.69%

z% * 66 = 69
z/100 * 66 = 69
z = 69 * 100 / 66 = 104.55% ... 4.55%

The correct result would be Ann (60 inches).
