Question

the product of two rational numbers is-12 if one of the number is -8 , find the other.

Iska answer 3/2 leke aa jao koi.......??​

Answer 1

Answer:

3/2

Step-by-step explanation:

let the other number be x

so -8×x=-12

X=12/8

=3/2

Answer 2

• The other number = $\bf\dfrac{3}{2}$

Given :

• The product of two rational numbers = –12.
• One of the number = –8.

To Find :

• The other number.

Solution :

Let,

The other number be x.

According to the question,

The product of two rational numbers is –12.

★ One number × Other number = –12

Given,

• One number = –8.

$\\ \bf \implies - 8 \times x = - 12 \\ \\ \\ \bf \implies x = \dfrac{ \not- 12}{ \not- 8} \\ \\ \\ \bf \implies x = \dfrac{ \not12}{ \not8} \\ \\ \\ \bf \implies x = \dfrac{ \not6}{ \not4} \\ \\ \\ \bf \implies x = \dfrac{3}{2} \\ \\ \\ \: \: \: \bf \therefore \: \: \: x = \dfrac{3}{2}$

Hence,

The other number is $\bf\dfrac{3}{2}$.

Verification :

Given,

The product of two rational numbers is –12.

According to the question,

★ One number × Other number = –12

Now we have,

• One number = –8.
• Other number (x) = $\bf \dfrac{3}{2}.$

$\\ \bf \implies - 8 \times x = - 12 \\ \\ \\ \bf \implies - 8 \times \dfrac{3}{2} = - 12 \\ \\ \\ \bf \implies \dfrac{ - 8}{1} \times \dfrac{3}{2} = - 12 \\ \\ \\ \bf \implies \dfrac{ - 8 \times 3}{1 \times 2} = - 12 \\ \\ \\ \bf \implies \dfrac{ \not-24}{ \not2} = - 12 \\ \\ \\ \bf \implies - 12 = - 12$

Hence Verified !
