Anthony had $280. Johnnie had $420. What is the ratio of Anthony's money to Johnnie's money?

2:3 / 2

1:1.5 is the answer

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)
