Question

Product of two rational numbers is -5/6 and one of the numbers is 1/3 find the other number.

Answer 1

Answer:

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

Step-by-step explanation:

Let a and b are two Rational numbers.

a = 1/3 , b = ?

a×b = -5/6 ( given )

$\frac{1}{3} \times b = \frac{-5}{6}$

$\implies b = \frac{-5}{6}\times \frac{3}{1}$

$=\frac{-5}{2}$

Therefore,

$Second\: number (b)= \frac{-5}{2}$

Answer 2

Answer:

product=-5/6

x=-5/6×3/1

x=-5/2

or

x=-2.5
