Decomposing Dividends

The video tutorial explains the concept of decomposition, illustrating how it applies to both physical objects and numbers. It demonstrates how to decompose numbers for easier division, using examples with both small and large numbers. The tutorial also compares different methods of decomposition through a problem-solving scenario involving two students, Michael and Lindsay. The lesson concludes with tips on effectively decomposing dividends for division.

What does the term 'decompose' mean in the context of this lesson?

• To combine into larger pieces

• To break down into smaller or simpler pieces

• To add numbers together

• To multiply numbers

In the division problem 143 / 11, how is the number 143 decomposed?

• 130 + 13

• 120 + 23

• 110 + 33

• 100 + 43

What is the quotient when 1875 is divided by 15 after decomposition?

• 120

• 115
