    i)

    The maximum error of the thickness of a piece of paper,

    =(1 ÷ 2)mm

    = 0.5mm

    ∴The maximum error of the thickness of a piece of paper is 0.5mm.

    ii)

    The thickness of each piece of paper,

    =(58 ÷ 500) mm

    =0.116 mm

    ∴The thickness of each piece of paper is 0.116 mm.

    The % error,

    =0.5/0.116 × 100%

    =4.3%,cor. to the nearest 0.1%

    2.
