Let the ratio=x

Then,Number of boys = 5x

Number of girls= 7x

Total students = 5x+7x = 12x

Fraction of boys = Number of boys÷Total students=5x÷12x=5/12

Fraction of girls= Number of girls÷Total students= 7x÷12x=7/12

Answer:

2/3

Step-by-step explanation:

Given that ,

  • n(male ) = 4
  • n ( female) = 8

→ n ( men + female ) = n(male ) + n(female)

→ n ( men + female ) = 4 + 8

→ n ( men + female ) = = 12

Therefore :-

→ Fraction of females = 8/12

→ Fraction of females = 2/3

Hence the required answer is 2/3.
