Answer:
Gabriel has the highest proportion of wins, so he should start.
Step-by-step explanation:
He should start the quarterbacks with the highest proportion of wins.
The proportion of wins is the number of games won divided by the number of games played(wins + losses).
We have that:
Germaine has 8 wins in 8+5 = 13 games. So his proportion of wins is 8/13 = 0.6154.
Gabriel has 7 wins in 7+4 = 11 games. 7/11 = 0.6364
Gabriel has the highest proportion of wins, so he should start.
