if the ratio of girls to boys is 5:2, then G = (5/2)B (that is, when B = 2, G = 5).
that is, ratios are represented algebraically by fractions.
I have a problem where there are six more girls than boys and the ratio of girls to boys is 5:2.
Now I can represent first statement as G = B + 6.
But how do I represent the 5:2 ratio algebraically. This seems as if it should be very basic but can't seem to get my head around it.
If total number of children had been mentioned I could have said total = 5G + 2B But I have no total. so how do I do it?
I am most interested in how to represent the ratio 5:2 algebraically than an answer to the problem.

If total number of children had been mentioned,
. . I could have said: total = 5G + 2B. . no
But I have no total . . . so how do I do it?
We are given: . . . . . which can be written: .
Substitute. .and get: .
If we knew the total number of children,
. . we could write: .
