Question

the product of two rational numbers is 18 by 35 if one of them is minus 2 by 5 find the other​

Answer 1

$product \: = \frac{18}{35}$

$One \: number = -\frac{2}{5}$

$So, other \: number \: is \: \frac{18}{35}÷\frac{-2}{5}$

Therefore ,

$\frac{18}{35}×\frac{-5}{2}$

Simplified ,

$\frac{-9}{7}$

Answer:-

$\frac{-9}{7}$

Answer 2

Answer:

-9/7

Step-by-step explanation: (approach should be break the question and answer)

product of 2 rational numbers is 18/35

if one of them is -2/5 find the other​

let the other be x

$(x)(\frac{-2}{5}) = \frac{18}{35}\\\\x = (\frac{18}{35}) (\frac{5}{-2}) \\\\x = \frac{-9}{7}$
