Answer:
7:13
Step-by-step explanation:
Since Eli has 7 games and his sister has 6 more than him, first you would add 7 to 6 and would get 13.
7 + 6 = 13
After you add, since the question is asking which ratio compares the number of games on Eli's phone compared to the number of games on his sister's phone, the number of Eli's games would go first, and then his sister's number of games would be the second number in the ratio, leaving you with 7:13.
