In last night’s baseball game, there were 4 walks and 15 hits. express the ratio of walks to hits, written in three different ways.

First let's define the variables:
 w = walks
 h = hits
 Then, we write the ratios which can be written as:

 Way 1:
 (w) / (h) = (4) / (15)
 (w) / (h) = (8) / (30)
 (w) / (h) = (16) / (60)

 Way 2:
 w: h
 4:15
 8:30
 16:60

 Way 3:
 w to h
 4 to 15
 8 to 30
 16 to 60
  
 The three distinct ways are shown, and three equivalent expressions are shown for each way.
