1/3 of a class are girls.
Elenna [48]

Ratio of girls to boys is (1/3*X) / (2/3*X).

That is, 1:2

Similarly, ratio of boys to girls is (2/3*X) / (1/3*X).

That is, 2:1

Step-by-step explanation:

  • Assume, total Number of students in the class is X.  Since, 1/3 part of the class is girls, this makes 2/3 part of the class boys.
  • Total number of girls will be equal to 1/3 *X. Total number of boys is equal to 2/3*X.
  • So, ratio of girls to boys is (1/3*X) / (2/3*X). That is, 1:2. Similarly, ratio of boys to girls is (2/3*X) / (1/3*X). That is, 2:1
