Respuesta :

15 / (15 + 12) = 15/27 = 5/9

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
