Respuesta :
Answer: 5/9
Step-by-step explanation:
Number of women= 15
Number of men= 12
Total number of people= 15+12 = 27
Fraction made up of women= Number of women divided by total number of chorus
= 15/27
We reduce 15/27 to it's simplest form = 5/9
The fraction of the chorus made up of women is 5/9
