a length of a tunnel on a construction plan is 1 1/4 feet long. The actual tunnel is to be 18 1/3 yards long. What will be the ratio, in simplest form, of the length of the actual tunnel to the length on the construction plan?
1 1/4/ (18 1/3 x 3) = 1.25 ft /55 ft = 1/44 or 1:44 scale
18 +1/3 yards = 55ft 1 + 1/4 ft = 1.25 ft
So
55 / 1.25 = 44 / 1 [ or, 44 : 1 ]
Although the scale is 1:44 the question asks for the ratio of the actual tunnel TO the plans so cphill has it right 44:1
