Decomposing Multiplication Problems

The video tutorial explains how to use decomposing to simplify multiplication problems. It begins with an introduction to the concept of decomposing numbers, followed by three examples: multiplying 25 by 5, 374 by 3, and 1234 by 6. Each example demonstrates breaking down the numbers into smaller parts, multiplying each part separately, and then adding the results to find the final product.

What does the term 'decomposing' mean in the context of multiplication?

• Breaking down numbers

• Combining numbers

• Multiplying numbers

• Dividing numbers

In the example of 25 times 5, what is the first step in decomposing 25?

• Multiply 25 by 5

• Add 20 and 5

• Subtract 5 from 25

• Break 25 into 20 plus 5

After decomposing 25 into 20 plus 5, what is the result of 20 times 5?

• 10

• 50

• 25

• 100

What is the final product of 25 times 5 after decomposing and solving?

• 75

• 150

• 125

• 100

In the example of 374 times 3, what is the expanded form of 374?

• 374

• 300 plus 74

• 370 plus 4

• 300 plus 70 plus 4

What is the result of 300 times 3 in the example of 374 times 3?

• 900

• 600

• 1200

• 300

What is the final product of 374 times 3 after decomposing and solving?

• 1222

• 1022

• 1112

• 1122

In the example of 1234 times 6, what is the expanded form of 1234?

• 1000 plus 200 plus 30 plus 4

• 1200 plus 34

• 1000 plus 234

• 1234

What is the result of 6 times 1000 in the example of 1234 times 6?

• 1000

• 6000

• 600

• 1200

What is the result of 6 times 200 in the example of 1234 times 6?

• 1000

• 200

• 600

• 1200
