Answer 2

ANSWER:

• Other rational number = 4

GIVEN:

• Product of two rational number is -16/9
• One number = -4/9

TO FIND:

• Other rational number.

SOLUTION:

Let x be the other rational number.

According to the Question:

$\implies \: \dfrac{ - 4}{9} \times x = \dfrac{ - 16}{9} \\ \\ \implies \: \dfrac{ - 4x}{9} = \dfrac{ - 16}{9} \\ \\ \implies \: x \: = \dfrac{ - 16}{9} \times \dfrac{9}{ - 4} \\ \\ \implies \: x \: = 4$

Other rational number = 4

NOTE:

• This type of question can be solved by first supposing the required number be x or any variable
• Find the expression and find the value of the variable.
