Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls = and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example :
is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.
