Which of the following girls will have the greatest percent of change in height if they each grow 3 inches over the summer?

Girl Current Height

Ann 60 inches

Betty 62 inches

Carol 64 inches

Diana 66 inches

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).
