Answer 2

Given :–

• Product of two rational numbers = 15.
• One of the number = $\sf \dfrac{-2}{3}$

To Find :–

• The other number.

Solution :–

Let

The other number be x.

According to the condition,

One number × Other number = Product of both numbers

Here the given values are,

• One number = $\sf \dfrac{-2}{3}$
• Product of two rational numbers = 15.

So,

$\rightarrow \dfrac{ - 2}{3} \times x = 15$

$\rightarrow \dfrac{ - 2}{3} \times \dfrac{x}{1} = 15$

$\rightarrow \dfrac{-2x}{3} = 15$

$\rightarrow -2x = 15 \times 3$

$\rightarrow -2x = 45$

$\rightarrow x = \dfrac{-45}{ 2}$

Hence,

The other number is $\sf \dfrac{-45}{2}$

Verification :–

One number × Other number = Product of both numbers

• One number = $\sf \dfrac{-2}{3}$
• Other number = $\sf \dfrac{-45}{2}$
• Product of both numbers = 15.

$\rightarrow \dfrac{ \cancel{-2}}{3} \times \dfrac{-45}{ \cancel{2} } = 15$

$\rightarrow \dfrac{-1}{ {3} } \times \dfrac{ {-45}}{1} = 15$

$\rightarrow \dfrac{\cancel{-}1 \times (\cancel{-}45)}{3 \times 1}$

$\rightarrow \dfrac{1 \times 45}{3}$

$\rightarrow \cancel \dfrac{45}{3} = 15$

$\rightarrow15 = 15$

Hence Verified !!
