Answer:
- shortest: 11 1/8 in
- longest: 11 3/8 in
Explanation:
It should be no surprise that the shortest allowable length is the nominal length less the full allowed tolerance:
11 1/4 - 1/8 = 11 1/8 . . . inches
__
Likewise, the longest allowable length is the nominal length plus the maximum tolerance:
11 1/4 + 1/8 = 11 3/8 . . . inches
_____
Of course, you know that 1/4 = 2/8, so adding or subtracting 1/8 gives the fractions shown above.
