Answer 1

Rose, ratios are exactly that. It works like fractions. If there are 15 red cars and 20 blue cars, the ratio of red to blue is 15:20 but we reduce that to 3:4, meaning that for every 3 red cars there are 4 blue cars. 

 

That means if there are 3 red, then there are 4 blue. If there are 75 red, then there are 100 blue.

 

Yes, we can also reverse it and say that for every 4 blue, there are 3 red, but that would read 4:3.
