Summary

  1. A ratio is a comparison of two numbers by division
  2. 'a', 'b', and 'x' are variables here

    2. 'a' and 'b' are variables here
    1. In math, the colon symbol in the middle represents a ratio
    2. 'a' and 'b' are variables here
    1. 'a' and 'b' are variables here
    1. Since a ratio is a comparison by division, '4' divided by '5', or '4/5', is a ratio
    1. 'x' is the variable in this example
    1. Two numbers can be represented by two variables, so ratios can also be made up of variables!
