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.

[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.
