Anthony had $280. johnnie had $420. what is the ratio of anthony's money to johnnie's money?

Do you know how to use a ratio table??

its pretty much like simplifying fractions:

so 280:420, and then we want to divide both sides by 280, resulting in a 1:1.5 ratio. 
your final answer is...

1:1.5 (or one to one and a half ratio)
