Question

The product of two rational numbers is -7. if one of them is -8/11. find the other

Answer 1

The other number is  $\frac{77}{8}$ .

Step-by-step explanation:

We are given that the product of two rational numbers is -7 and one of them is -8/11.

Let the other rational number be x.

SO, according to question;

      Product of two rational numbers = -7

                          $\frac{-8}{11} \times x$  =  -7

                             $\frac{-8x}{11} = -7$

                              $x=\frac{-7 \times 11}{-8}$

                              $x=\frac{77}{8}$

Therefore, the other rational number is  $\frac{77}{8}$ .
