Answer:
X+7
Step-by-step explanation:
If the youngest child's age expression is X+3 then the middle child's would be x+5 and the oldest would X+7. Even numbers have a difference of 2 between them and that is why 2 is gradually added to each age expression. Hope that helps.

They are not equivalent fractions.
