Question

the product of two rational number is -5/16. if one of them is 4/18 the other.​

Answer 1

Give :

The product of 2 rational numbers = -5\16

One number (x) = 4/18

Another number (y) = ?

Solution :

x × y = -5/16

(4/18) × y = -5/16

y = (-5/16) × (18/4)

y = -45/32

Therefore, another rational number is ' -45/32 '.

Answer 2

${\mathscr{\red{\bold{Heya! }}}}$

Let the unknown number be x,

$\\ \frac{4}{18} \times x = \frac{ - 5}{16} \\ x = \frac{ - 5}{16} \times \frac{18}{4} \\ x = \frac{ - 90}{64} \\ x = \frac{ - 45}{32}$

${\boxed{\bold{\red{-45/32}}}}$
