A fraction is a number that represents a part of the whole or a part of the group. If we picture a cake, the denominator tells us how many slices to slice the cake and the numerator tells us how many of those slices we can have. On the other hand, a ratio is a comparison of two quantities.
In a group of five students containing 4 boys and 1 girl, the fraction of females is 15. The fraction of males is 45. The denominator will always be five because the whole group consists of five students.
In the example given above, the ratio of girls to boys is 1:4 and the ratio of the number of boys to the number of girls is 4:1. The ratio of girls to the total number of students is 1:5, and the ratio of boys to the total number of students is 4:5.
