ratio of x to y to z

English 1b3 ratio of x to y to z

I'm wondering if you have invented a new mathematical concept. As far as I know, a ratio is a relationship between two numbers, not three. I'd write something like these:

1. What is the ratio of ads that target girls to ads that target boys?
2. What percent of ads that target either girls or boys target girls, an

There is also the possibility that you mean "What is the ratio of adds that target one gender to ads that target both?"

Given ads that target children, how many, by percentage, target only girls (boys)?
Given ads that target children, how many, by percentage, target both boys and girls?

The three percentages, girls only, boys only, and both have to add up to 100%

Yes, I noticed, but decided to be discreetly quiet about it. Naturally, my spell checker saw nothing unusual there.

GPYFor example, you could say that the sides of a triangle are in the ratio 3:4:5.

There you go! And a right triangle too! I thought maybe there was an example. But thank the gods you didn't use 39:80:89! I'd never have recognized that one!

Still, I can't see it as a meaningful group of three numbers in the case of advertisements. What woul
