Answer:
j < 14
Explanation
it's pretty simple but some people may think it's complicated so let me help you out! if Sophie is 14 it does not show jakes age so in estimation you would estimate that jake is younger that its only j so the answer would be j<14 to go in further detail jakes years do not compare to sophies age and that is because his age in the question is hidden. HOPE THIS HELPS!
