Question

The product of two rational number is 5/9 If one of the rational number is -8/21, find the other​

Answer 1

Answer:-

Given:

Product of the two rational numbers is$\frac{5}{9}$

To find:

The other number.

Solution:

One rational no. = -8/21

Product = 5/9

Let the other rational no. be x.

According to the question:

$\frac{ - 8}{21} \times x = \frac{5}{9}$

$x = \frac{5 \times 21}{9 \times - 8}$

x= $- \frac{35}{24}$

$x = - 1 \frac{11}{24}$

Thus, the required rational no. is

$- 1 \frac{11}{24}$

Answer 2

other number is -35/24
