Question

4. The product of two rational numbers is-28/45 if one of them is 14/9find the other ​

Answer 1

Step-by-step explanation:

Hi Dear !!

Let the other rational number be X.

First rational number = 14 / 9

Second rational number = x

Product of two rational numbers = -28 / 45

First number × Second number = -28/45

14/9 × X = -28/45

X = -28 × 9 / 45 × 14

X = -2 / 5 .

Hence,

Second rational Number = X = -2/5

Hope it will help you :))

Answer 2

The product of two rational numbers= -28/45

One of them= 14/9

$Other \: number = \frac{ - 28}{45} \div \frac{14}{9} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ - 28}{45} \times \frac{9}{14} = \frac{ - 2}{5}$

Therefore, the required number is -2/5
