A ratio is a comparison between two (or more) different quantities of the same unit.
A ratio does not tell us how many there are altogether, only how their numbers compare.
For example if the numbers of bananas and apples in the fruit basket are in the ratio 2:1, we know the following information:
– There are more bananas than apples.
– There are 2 bananas for every apple
– The number of bananas is double the number of apples, which is the same as saying there are half as many apples as bananas.
Final Answer:-
It says that the the first thing is double than the second thing.
