Exercise 44 Page 176

The product of a number and its reciprocal is 1.

2/3

Practice makes perfect

The product of any nonzero real number and its reciprocal is 1. x*1/x=1For a fraction, the reciprocal is the inverse of the fraction. x/y*y/x=1 Therefore, the reciprocal of 32 is 23. Let's check that this is true by calculating the product.

3/2* 2/3? =1

Multiply fractions

3* 2/2* 3? =1

Multiply

6/6? =1

a/a=1

1=1

We were able to confirm that the reciprocal of 32 is 23.
