Question

The length of a rope is 2 m and its diameter is 1 mm. Find the ratio of length of the rope to its diameter.

• A. 200:1
• B. 2000:1
• C. 1:2000
• D. 2:1

Answer 1

The correct option is B

2000:1

The ratio is the method of comparison between two similar quantities having the same unit.

Length = 2 m = 2000 mm and diameter = 1 mm

Hence ratio of the length of rope to its diameter is

$\frac{2000}{1}=2000:1$
