What is the upper limit if a tolerance is given as 4 3/4 plus or minus 1/64

4 & 49/64

whole part = 4

fractional part = 49/64

Work Shown:

U = upper limit

U = (center) + (margin of error)

U = (4 & 3/4) + (1/64)

U = (4 + 3/4) + (1/64)

U = 4 + (3/4 + 1/64)

U = 4 + (48/64 + 1/64)

U = 4 + 49/64

U = 4 & 49/64

0.02
