• Another Number is 4/7

$\rule{200}{0.5}$

$\underline{\underline{\mathfrak{Step-By-Step-Explanation :}}}$

Given :

• Product of Rational numbers is 1/3
• One of the number is 7/12

$\rule{200}{1}$

To Find :

• Another number

$\rule{200}{1}$

Solution :

Let the another rational number be x

A.T.Q,

$\implies {\sf{x \: \times \: \dfrac{7}{2} \: = \: \dfrac{1}{2}}} \\ \\ \implies {\sf{x \: = \: \dfrac{\dfrac{1}{3}}{\dfrac{7}{12}}}} \\ \\ \implies {\sf{x \: = \: \dfrac{1 \: \times \: 12}{3 \: \times \: 7}}} \\ \\ \implies {\sf{x \: = \: \dfrac{4}{7}}} \\ \\ \underline{\sf{\therefore \: Another \: Rational \: Number \: is \: \dfrac{4}{7}}}$

$\rule{200}{2}$

• Numbers which are divisible by 2 and itself are called Even Numbers.

• Numbers which are not divisible by 2 are called Odd Numbers.

• The Numbers are which can be written in form of p/q are called Rational Numbers.

• The numbers which can't be written in form of p/q are called Non-Rational Numbers.
