Division Is Multiplying by the Inverse

You can use what you know about multiplication to find the answer to a division problem.

Consider this division problem: 12 ÷ (−3).

You know that dividing is the same as multiplying by the inverse (4 ÷ 2 is the same as 4⋅12).

  • How could you rewrite 12 ÷ (−3) as a multiplication problem using the inverse of −3?
  • What is the answer?
  • What is the answer to the original division problem?
