The answer is: " 2 :5 " ; or, write as: " 2/5 " .

________________________________________________________

The ratio of 'girls' to 'all students' is: "2: 5 " ; or, write as: " 2/5 ".

________________________________________________________

Explanation:

________________________________________________________

Given: The ratio of boys to girls is: " 3:2 " .

Problem: Find the ratio of "girls" to "all students:

________________________________________________________

Note: This ratio of "boys to girls", which is " 3 : 2 " ;

________________________________________________________

→ can be expressed as " 3x: 2x" ;

in which the total number of students is: " 3x + 2x " = 5x " .

→ The total number of students is represented as: " 5x " .

________________________________________________________

→ The ratio of "girls to boys" is: "2x : 3x" .

→ {that is; the "inverse" of the ratio of "boys to girls"} ;

→ {that is; the "inverse" of " 3x: 2x" } ; → which is: " 2x : 3x " .

________________________________________________________

The ratio of "girls" to "all students" is: "2x : 5x " ; or " 2x/5x " ;

→ Both "x" values cancel ; {since: " x/x = 1 "} ;

_________________________________________________________

→ and we have the answer: " 2 :5 " ; or, write as: " 2/5 " .

_________________________________________________________

The ratio of 'girls' to 'all students' is: " 2 :5 " ; or, write as: " 2/5 ".
