Question

prouduct of rational no. is 10 .If one of them is -3/5.find the other

Answer 1

-50/3 is the answer that you get because -3/5 × -50/3 = 10

Answer 2

Given that product of two rational numbers is 10

and one is
$- \frac{3}{5}$

So let the other be 'x'

From the question,

$x \times - \frac{3}{5} = 10 \\ \\ x = 10 \times - \frac{5}{3} \\ \\ x = - \frac{50}{3}$
So other number is - 50/3
