8-37.

Simplify each of the following expressions.

For help with parts (a), (b), and (c), refer to the lesson 6.2.4 and 6.2.6 Math Notes boxes.

The answer for part (b) is

. You will want to convert the mixed number to a fraction before multiplying.

When two numbers have a product of one, they are called reciprocals or

**multiplicative inverses**. What is the reciprocal or multiplicative inverse of each of these numbers?

For part (d), it may help to look back at part (b) of this problem.

Do you notice a way to apply that expression and solution to this question?

It may also help to turn parts (ii) and (iii) into fractions.

Did you find the answer to (ii)?
