2. \(35 ÷ 5 = ?\) (
   Solution

   x

   Solution: 7
   Details:
   Division is the inverse of multiplication. These two operations undo each other.
   \(35 \div 5\)
   
   The problem can be written in terms of multiplication. The missing number will solve this multiplication problem and the original division problem.
   \(5 \times {\boxed{\color{red} ?}} = 35\)
   
   The problem is solved by multiplying by \(5 \times 7\) to get 35.
   \(5 \times {\boxed{\color{red} 7}} = 35\)
   
   The division problem that includes the same numbers as the multiplication problem above, has one of its numbers in the answer.
   \(35 \div 5 = {\color{red} 7}\)
   
   The answer to 35 divided by 5 is 7.

   Solution: 6
   Details:
   Division is the inverse of multiplication. These two operations undo each other.
   \(48 \div 8\)
   
   The problem can be written in terms of multiplication. The missing number will solve this multiplication problem and the original division problem.
   \(8 \times {\boxed{\color{red} ?}} = 48\)
   
   The problem is solved by multiplying by \(8 \times 6\) to get 48.
   \(8 \times {\boxed{\color{red} 6}} = 48\)
   
   The division problem that includes the same numbers as the multiplication problem above, has one of its numbers in the answer.
   \(48 \div 8 = 6\)
   
   The answer to 48 divided by 8 is 6.
