This video tutorial explains how multiplying a number by a fraction equal to one does not change its value, using the multiplicative identity property. It demonstrates this concept with examples and visual representations, emphasizing the importance of understanding fractions where the numerator and denominator are the same. The tutorial also addresses common misunderstandings related to this concept, ensuring students grasp the idea that multiplying by a fraction equal to one results in the original number.

What does the multiplicative identity property state?

• The product of any number and one is that number.

• The sum of any number and one is that number.

• The difference of any number and one is zero.

• The product of any number and zero is zero.

If a fraction has the same numerator and denominator, what is its value?

• One

• The numerator

• Zero

• The denominator

How does multiplying a number by a fraction equal to one affect the product?

• It makes the product zero.

• It keeps the product the same.

• It halves the product.

• It doubles the product.

What is the result of multiplying 7 by 2/2?

• 14

• 7

• 1

• 0

Why is 7 * 2/2 not equal to 14?

• Because multiplying by 2/2 is the same as multiplying by one.

• Because 7 is not a multiple of 2.

• Because 2/2 is not equal to one.

• Because 14 is not a valid product.
