The wheel stagger of an automobile is the difference between the axle-to-axle lengths on the right and left sides. if this length is 101 1/4 on the right side of a particular car and is 100 3/8 on the left side, find the wheel stagger of this automobile.

From the given, we already know that the unknown wheel stagger of the automobile is the difference between the lengths on the right side and the left side. This can be expressed as,
                    wheel stagger = Length in right side - length in left side

Substituting the known values.
                  wheel stagger = (101 1/4) - (100 3/8)
We convert numbers to improper fraction,
                  wheel stagger = 405/4 - 803/8
We let x be the length of wheel stagger.
         x = 405/4 - 803/8
Multiply the equation by 8,
        8x = (810 - 803) 
         8x = 7
Divide the equation by 8,
           x = 7/8

ANSWER: 7/8
