Question

The product of two rational number is 1/2 if one of the m is -2/15the other number is

Answer 1

let one no. be x

x × - 2/15 = 1/2

By using transposition method

x= 1/2 / 2/15

x = 1 × 15 / 2 × 5

x = 15/4

Answer 2

Answer:

Let the other number = x

Given x * -2/15 = 1/2

x = 1/2

-2/15

x = 1/2 * -15/2

x = -15/4

X = -15/4
