Jermaine has t subway tokens. karen has 4 more subway tokens than jermaine. raul has 5 fewer subway tokens than jermaine. which expression represents the ratio of karen’s tokens to raul’s tokens

The first thing we must do is to build the expression based on what we are told in the enunciation:
 Jermaine has t subway tokens:
 t
 Karen has 4 more subway tokens than Jermaine
 t + 4
 Raul has 5 fewer subway tokens than Jermaine
 t + 4 - 5 = t -1
 the ratio of Karen's tokens to Raul's tokens
 Ratio: (t + 4) / (t-1)
 answer
 Ratio: (t + 4) / (t-1)
