E. Use the Distributive Property to show the partial products shown in your area model.
6 × HMH Into Math Grade 5 Module 2 Lesson 1 Answer Key Relate Multiplication to Division 7 = 84
___ + ___ = 84
(6 × __) + (6 × ___) = 84
___ × (___ + ___) = ___
____ × ____ = ____

F. What related division equation can you write to model the number of photos each friend will get?
________________

Answer:
Given,
Simone wants 6 of her friends to share 84 photos equally.
84 ÷ 6 = 14
Let the unknown factor be x.
6 × x = 84
x = 14
(6 × 7) + (6 × 7) = 84
6(7 + 7) = 84
6 × 14 = 84
Thus each friend will get 14 photos.

Question 2.
Model with Mathematics Four people make a playlist of 76 songs for a party. Each person provides the same number of songs for the playlist. How many songs does each person provide?

  • Draw to represent the situation. ____________
  • Write a multiplication equation and a division equation to model the situation. ____
  • How many songs does each person provide? _____

Answer:
Given,
Four people make a playlist of 76 songs for a party.
Each person provides the same number of songs for the playlist.
4 × x = 76
x = 76/4
x = 19
Thus each person provides 19 songs.

Question 3.
Attend to Precision Nine friends collect 1,260 leaves at the forest preserve. They each collect the same number of leaves. Explain how to use an equation to find the number of leaves each friend collects.
____________________
____________________
Answer:
Given,
Nine friends collect 1,260 leaves at the forest preserve.
They each collect the same number of leaves.
9 × x = 1260
x = 1260/9
x = 140
9 × 70 + 9 × 70 = 1260
9 (70 + 70) = 1260
630 +630 = 1260
Thus each friend will collect 140 leaves.
