The length of a table is 2m and its breadth is 50cm. Find the ratio of the length of the table to its breadth.
4:1
2:1
The ratio is obtained when two quantities are of the same unit. So, first we convert either metre to centimetre or vice-versa. Length of the table in centimetres is equal to 200 and breadth is 50cm, so the ratio of the length of the table to its breadth is 20050=41
