The heights of three students are listed below. Ability 67.26 inches

Rebecca 68.18 inches

Gabby 66.83 inches

What is the difference between the greatest and least height?

The greatest height is 68.18 inches and the least height is 66.83 inches.

To find the difference between the two, you subtract the least height from the greatest height:

68.18 inches - 66.83 inches = 1.35 inches

Therefore, the difference between the greatest and least height is 1.35 inches.
