### Example Question #53 : Fractions

Which of the following statements demonstrates the inverse property of multiplication?

**Possible Answers:**

None of the examples in the other responses demonstrates the inverse property of multiplication.

**Correct answer:**

The inverse property of multiplication states that for every real number, a number exists, called the multiplicative inverse, such that the number and its inverse have product 1. Of the statements given, only

demonstrates this property.

### Example Question #4 : Multiplicative Inverse Property

Which of the following displays the multiplicative inverse property?

**Possible Answers:**

**Correct answer:**

The mulitplicative inverse property deals with reciprocals. For example, the multiplicative inverse, or reciprocal, of the number 7 is .

The multiplicative inverse property states that a number times its multiplicative inverse equals 1.

Therefore,
