Question

the product of rational numbers is 12/5 if one of them is -3/5 find the other ​

Answer 1

one rational no.=-3/5

let other be x

product of rational nos. is a 12/5

A.T.Q

(-3/5)x=12/5

-3/5x=12/5

x=12/5×-5/3

x=-4

Answer 2

Answer:

-4

Step-by-step explanation:

$one \: rational \: no.is = \frac{ - 3}{5} \\ let \: the \: other \: rational \: no. = x \\ product \: of \: rational \: no = \frac{12}{5} \\ then. \\ ...... \frac{ - 3}{5} \times x = \frac{12}{5} \\ x = \frac{12}{5} \div ( \frac{ - 3}{5} ) \\ x = \frac{12}{5} \times ( \frac{ - 5}{3} ) \\ x = \frac{ - 60}{15} = \frac{12}{3} = - 4......$
