Question

The product of two rational numbers is -3/25 .If one of them is 5/12 find the other.
option
a) 1/12
b) -36/125
c) 1/125
d) 5/125
​

Answer 1

Answer:

b) -36/125

Step-by-step explanation:

Let the other number be x.

x * 5/12 = -3/25

x = -3/25 ÷ 5/12 = -36/125

Therefore the other number is -36/125

I hope you found the solution helpful :)

Answer 2

Answer:

b) -36/125

Step-by-step explanation:

let a and b are two rational numbers

let a and b are two rational numbers then

let a and b are two rational numbers thena x b = - 3/25

let a and b are two rational numbers thena x b = - 3/25let b = 5/12

let a and b are two rational numbers thena x b = - 3/25let b = 5/12now

let a and b are two rational numbers thena x b = - 3/25let b = 5/12now a x 5/12 = - 3/25

let a and b are two rational numbers thena x b = - 3/25let b = 5/12now a x 5/12 = - 3/25a = _3/25 x 12/5

let a and b are two rational numbers thena x b = - 3/25let b = 5/12now a x 5/12 = - 3/25a = _3/25 x 12/5a= - 36/125
