Challenge Problem

In the problem about the baseball fields, the ratio of the high school field dimensions to the major league field dimensions is 2:3.

Suppose a local little league team wants to build a baseball field with measurements in a 1:3 ratio to those of the major league field.

  • How would your double number line change?
  • What would the ratio be between the little league field and the high school field?
