Question

The product of two rational numbers is -20/9 . If one of the number is 4 , then the other

Answer 1

Answer:

4 * a = -20/9

a = -20/9 *1/4

a = -5/9

Answer 2

Given:

• Product of two Rational numbers is -20/9.
• One of the number is 4 .

To Find:

• The other number.

Answer:

Given that product of two Rational numbers is -20/9 and one of them is 4 .

Let us take other number be x .

Atq ,

$\sf{\implies x \times 4=\dfrac{-20}{9}}$

$\sf{\implies x = \dfrac{\cancel{-20}}{9\times \cancel{4}}}$

$\bf{\leadsto x =\dfrac{-5}{9}}$

Hence the other Rational number is -5/9.

→ Rational Numbers:

• The number in the form of p/q where p and q are integers and q ≠ 0 is called Rational number. For ex - 3 , 5 , ¾ , ⅞ , -8 , etc.

→ Integers :

• All counting numbers, their negatives along with 0 are called Integers. For ex - -1,0,5,6,etc.
