Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.
In order to determine the height of the higher board, divide the height of the lower board by 25%.
Height of the higher board = 3 feet / 25%
3 / 0.25 = 12 feet
12 feet + 12 feet = 24 feet
