You want to place a towel bar that is 24 1⁄4 centimeters long in the center of a door that is 70 1⁄3 centimeters wide. How far should you place the bar from each edge of the door? (Write the answer as a mixed number.)
From this picture we can see that:
x + 24 + 1/4 + x = 70 + 1/3
2x + 24 + 1/4 = 70 + 1/3
2x = 70 + 1/3 - 24 - 1/4
x = (70 + 1/3 - 24 - 1/4) / 2
x = 553/24
x = 23 + 1/24 cm
