Question

A rational number is such that when you multiply it by - and add
to the product,
you get
_. What is the number?​

Answer 1

Answer:

Step-by-step explanation:

let the rational number be x

multiply it with 5/2

product=5x/2

add 2/3 to the product

sum =(5x/2)+2/3

given sum = -7/12

solving ..

(5x/2) +  (2 /3 ) = -7/12

5x/2 = (-7/12) - (2/3)

5x/2 = (-15/12)

x = (- 1/2)

therefore the number is -1/2

Answer 2

Step-by-step explanation:

Hi,

Let the rational number = x

x is multiplued with 5/2 = 5x / 2

According to the problem given,

5x/2 + 2/3 = - 7/12

5x/2 = -7/12 - 2/3

5x/2 = ( -7 - 8 ) / 12

5x / 2 = -15 / 12

x = ( - 15 / 12 ) × ( 2 / 5 )

x = - 30 / 60

x = - 1 / 2

Therefore,

Required rational number = x = - 1/2

I hope this helps you.
