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
