Ratios about our Class

Ratios In a class of 20 students, 11 are female and 9 are male. Write the following rations to describe the class. a)Ratio of male to female students b)Ratio of female to male students c)Ratio of female students to the total d)Ratio of male students to the total e)Ratio of total number of students to females f)Ratio of total number of students to males

Ratios In a collection of 25 CDs, 17 are country music and 8 are classical music. Write the ratio of classical to country music in 3 different ways.

Ratios Ratios should be simplified (reduced), but never turned into mixed fractions.

Ratios Express the ratios in simplest form: a)15: 9 b)20 : 8
