Question

A length of a snake is 10 cm and that of a crocodile is 2 m. The ratio of length of the snake to that of the crocodile is ___

Answer 1

The ratio is a method of comparing two quantities having the same unit, so first convert either meter to a centimetre or vice-versa.

2 m = 200 cm

Hence the ratio of the length of the snake to that of the crocodile would be $\frac{10}{200}=\frac{1}{20}=1:20$.
