This year ⅗ of the students in Fionna’s class identify as girls. Fionna notices that ⅔ of these girls wear braces. Only ½ of the boys wear braces. What fraction of all the students in the class wear braces?

If girls are 3/5 of the class, then 2/3 * 3/5= 2/5 of the total class are girls who wear braces. That means that 2/5 of the class are boys and 1/2 of them wear braces, so 1/2 * 2/5= 1/5. The total amount of students that wears braces is 3/5 of the class.

 

 

Hope it helps!
