$- \frac{9}{2}$
$- 7$
$2.1$

Short Answer

Expert verified

(a). $- \frac{2}{9}$

(b). $- \frac{1}{7}$

(c). $\frac{10}{21}$

Step by step solution

Part (a). Step 1. Given Data

Number -

$- \frac{9}{2}$

Part (a). Step 2. To Find

Find the multiplicative inverse of number.

Part (a). Step 3. Explanation

The multiplicative inverse of $- \frac{9}{2}$ is the reciprocal of $- \frac{9}{2}$ , which is role="math" localid="1647929772371" $- \frac{2}{9}$ . Therefore, the multiplicative inverse of $- \frac{9}{2}$ is $- \frac{2}{9}$ .

Part (b). Step 1. Given Data

Number -

$- 7$

Part (b). Step 2. To Find

Find the multiplicative inverse of number.

Part (b). Step 3. Explanation

The multiplicative inverse of -7 is the reciprocal of -7, which is $- \frac{1}{7}$ Therefore, the multiplicative inverse of -7 is $- \frac{1}{7}$ .

Part (c). Step 1. Given Data

Number -

2.1

Part (c). Step 2. To Find

Find the multiplicative inverse of number.

Part (c). Step 3. Explanation

To find the multiplicative inverse of 2.1, we first convert 2.1 to a fraction, $\frac{21}{10}$ . Then we find the reciprocal of the fraction. The reciprocal of $\frac{21}{10}$ is $\frac{10}{21}$ . So the multiplicative inverse of 2.1 is $\frac{10}{21}$ .
