Answer:
Jacob's fraction is 3/8 of the total reward (which translates to $30)
Explanation:
Given the ratio of Ethan : Jacob is 5:3,
expressing this as a fraction,
Ethan gets 5/ (5 + 3) = 5/8 of the total reward
Jacob gets 3 / (5+3) = 3/8 of the total reward.
if you are asked to find the value that Jacob receives,
Jacob receives, 3/8 x $80 = $30
