A scale drawing has a scale of 1/4 in : 12 ft. Find the actual lenght for 8 ft

Answer 1

1/4:12 = (1/4)(1/12) = 1/48

1/48 = x/8

x = 8(1)/48 = 8/48 = 1/6

Answer 2

Set it up as a proportion problem. I changed everything to inches and then converted back to feet at the end.

1/4 / 144 = 96/x

1/4x = 13,824

x = 55,296 inches

x = 4,608 feet
