## HMH Into Math Grade 3 Module 7 Answer Key Relate Multiplication and Division

What Is The Hidden Letter?

• Complete the equations. Then shade the factors or products on the hundred chart. • What letter do you see? ___ Turn and Talk
• Explain how finding the product for 2 × 8 = is different from finding the unknown factor for × 8 = 16. What does that tell you about the relationship between multiplication and division?

n = 2.

Explanation:
Gien the product is 2 × 8 = which is 16 and let the missing digit be n for the equation n × 8 = 16 where n is 16÷8 = 2. The relationship between multiplication and division is, here division is the inverse operation of multiplication.
