Question

the product of two rational numbers is (-18/75).If one of the rational numbrr is (-9/20),then find the other​

Answer 1

Answer:

Let the required rational number be = x

Other number = (-7/15)

Product of rational number = (-5)

⇒ (-7/15) × x = (-5)

⇒ -7x = (-5) × 15

⇒ X = (-75/-7) = 75/7

∴ The required rational number = 75/7

Answer 2

Answer:

let the other number be x then

x (-9/20) = -18/75

x = -18/75/9/30

= -18/75 × 30/9

= -540 / 700

= -54/70

= -27/35
