    4.23

    Step-by-step explanation:

    31 ¾ ÷ 7 ½

    make the mixed number into improper fraction

    and this will become,

    127/4 ÷ 15/2

    \frac{127}{4}   \div  \frac{15}{2}

    \frac{127}{4}   \times  \frac{2}{15}

    =  \frac{127}{30}

    =4.23

    Math Equation:

    31 1/2 ft ÷ 7 1/4 in


    Convert inch to ft

    12 inch = 1 ft

    7 1/2 in = 15/2 in

    15/2 in (1 ft / 12 inches)

    = 15/24 ft

    = 5/8 ft


    Math Equation after converting to ft:

    31 1/4 ft ÷ 5/8 ft

    Convert 31 1/4 to improper fraction:

    125/4 ft

    = 125/4 ft ÷ 5/8 ft

    Find their LCD

    LCD = 8

    = 250/8 ft ÷ 5/8 ft

    Changing the divisor using Reciprocal method

    = 250/8 ft x 8/5 ft

    Reduce to lowest term by cancel method

    = 50

    Convert fraction to decimal.
    31 1/4 = 31.25 ft
    7 1/2 = 7.50 in

    convert 31.25 ft to inches.
    31.25 \: ft \times \frac{12 \: inches}{1 \: ft} = 375 \: in
    [tex] \frac{375 \: in}{7.5 \: in} = 50 \: pcs

    there are 50 pcs of 7 1/2 in wire in a 31 1/4 ft rolled wire.
