Exercise 41 Page 176

The product of a number and its reciprocal is $1 .$

$\frac{1}{5}$

Practice makes perfect

The product of any nonzero real number and its reciprocal is

1 .

x \cdot \frac{1}{x} = 1

Therefore, the reciprocal of

5

is

\frac{1}{5} .

Let's check that this is true by calculating the product.

5 \cdot \frac{1}{5} = ? 1

DenomMultFracToNumber

$5 \cdot \frac{a}{5} = a$

1 = 1

We were able to confirm that the reciprocal of

5

is

\frac{1}{5} .
