Question

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

Answer 1

Given :-

Product of 2 number = -20/9

One number = 4

To Find :-

x

Solution :-

Let the second number be x

`\large \tt \: 4 * x = ( - 20)/(9)`

`\large \tt \: 4x = ( - 20)/(9)`

`\large \sf \: x = (-20)/(9) * 4`

`\large \tt \: ( - 20)/(9 * 4) = ( - 20)/(36)`

`{ \bf{ \red{ \underline{ x = (-5)/(9)}}}}`

Answer 2

`- (5)/(9)`

Explanation:

The product of two numbers is the resulting number after multiplying those 2 numbers together.

Let the other number be x.

`4x = - (20)/(9)`

To find x, divide both sides by 4:

`x = - (20)/(9) / 4 \\ x = - (20)/(36) \\ x = - (5)/(9)`

Thus, the other number is
`- (5)/(9)`.
