Question

The product of two rational numbers is -28/81, if one of the number is 14/27 then find the other no.

Answer 1

Answer:

Given:-

Product = $-\frac{28}{81}$

One of the number = $\frac{14}{27}$

Using A x B = C where A =  $\frac{14}{27}$ C = $-\frac{28}{81}$

⇒ $\frac{14}{27}$ x B = $-\frac{28}{81}$

⇒ B = $-\frac{28}{81}$ x $\frac{27}{14}$

⇒ B = - $\frac{2}{3}$
