McGraw-Hill My Math Grade 5 Answer Key Chapter 2 Lesson 6 Use Partial Products and the Distributive Property

Draw It

Darnel and his four friends went to an ice skating rink and bought sandwiches. They divided the total cost and found that each person needs to pay $17. What was the total cost for ice skating and sandwiches?

McGraw Hill My Math Grade 5 Chapter 2 Lesson 6 Answer Key Hands On Use Partial Products and the Distributive Property 1

McGraw-Hill-My-Math-Grade-5-Chapter-2-Lesson-6-Answer-Key-Hands-On-Use-Partial-Products-and-the-Distributive-Property-2
2. Add the partial products.
___ + ___ = ____
So, the total cost for ice skating and sandwiches was _____.
Answer:
The partial products are 50 + 35 = 85
So, the total cost for ice skating and sandwiches was 85.

When you use partial products, you are using a property. A property is a rule in mathematics that can be applied to all numbers. The property that you applied above is called the Distributive Property. You will learn more about this property in the next lesson.
