Answer 2

Given:

• The product of two numbers =  -20/9
• The value of one number = 4

To Find:

• The value of the other number.

Solution:

Let "x" and "y" be the two numbers. It is given that one number is 4 therefore let "x = 4". Now we should find the value of the other number "y".

We can form an equation from the given data. That is,

⇒ x×y = -20/9

substitute the value of "x" in the above equation. We get,

⇒ (4)×y=-20/9

rearrange the above equation in order to find the value of "y" by transferring "4" to the RHS.

⇒ y = (-20/9)/4

⇒ y = (-20/9)×(1/4) { cancel the divisible terms in the equation}

⇒ y = -5/9

∴ The value of the other number is -5/9.
