Question

the product of two rotional number is -8/9 if one of the number is 2/3 find the other number​

Answer 1

the product of two number = -8/9

one of the number =2/3

other number =?

other number = the product of two number divided by one of the number

= -8/9 ÷2/3

= -8/9 ×3/2

= -4/3

therefore the other number is -4/3

Answer 2

$\huge\textbf{Given:}$

$\text{Product of two rational numbers = -8/9}$

$\text{One of the rational number = 2/3}$

$\dag\huge\textbf{To find:}$

$\text{The other rational number?}$

$\huge\textbf{Solution:}$

$\text{Let the other rational number be x.}$

$\textbf{And,}$

$\text{Product of two rational numbers is 2/3x.}$

$\textbf{« Now, Forming an equation,}$

$\qquad\boxed{ \tt\rightarrow \: 2/3x = -8/9}$

$\qquad\boxed{\tt\rightarrow x = (-8/9)/(2/3)}$

$\qquad \boxed{\tt\rightarrow x = -4/3 × 1/1}$

$\qquad \boxed{\tt\rightarrow x = -4/3}$

$\textbf{∴ Hence, The other rational number is -4/3.}$
