1. Lilly used the equation \( 3 \times 9=27 \) to solve a problem. Which problem could Lilly have solved? A Emilio has 9 baseball cards. He gives 3 baseball cards to Amanda. How many baseball cards does Emilio have now? B Emilio has 9 baseball cards. He places the same number of baseball cards into each of 3 boxes. How many baseball cards are in each box? C Emilio has 9 baseball cards. Brandon has 3 times as many baseball cards as Emilio. How many baseball cards does Brandon have? D Emilio has 9 baseball cards. He buvs 3 more basehall sards Howim?

Lilly's equation \( 3 \times 9 = 27 \) suggests a scenario where something is being multiplied. In real life, this can relate to situations like sharing or distributing items. For instance, if Emilio puts 9 baseball cards into each of 3 boxes, that totals 27 cards! It shows how multiplication can be practical in organizing items. A common mistake in similar problems is confusing addition with multiplication! If you think Emilio just gave away or bought more cards without considering how they are divided into groups, you might mistakenly calculate the totals incorrectly. Always read the problem carefully to identify if you need to add or multiply based on the scenario described!
