Answer 2

Answer:

-7/120

Step-by-step explanation:

As per the provided information in the given question, we have :

• A rational number is such that when you multiply it by 5 and add to the product, you get -7/12.

We are asked to calculate the number.

Let us suppose the number as x.

― According to the question, the number is such that when you multiply it by 5 and add to the product, you get -7/12. Writing it in the form of an equation,

$\longmapsto\rm {5(Number) + Product = \dfrac{-7}{12} }$

Substitute the value of x. Product is the number which we'll get after multiplying x with 5.

$\longmapsto\rm {5x + 5x = \dfrac{-7}{12} }$

Performing addition of the like terms in L.H.S.

$\longmapsto\rm {10x = \dfrac{-7}{12} }$

Now, transposing 10 from L.H.S to R.H.S, its arithmetic operator will get changed.

$\longmapsto\rm {x = \dfrac{-7}{12}\div 10 }$

Performing division of the fractions in R.H.S.

$\longmapsto\rm {x = \dfrac{-7}{12}\times \dfrac{1}{10}}$

Performing multiplication in R.H.S and simplifying further.

$\longmapsto \underline{\boxed{\bf {x = \dfrac{-7}{120} }}} \; \bigstar$

∴ The number is -7/120.
