Question

The sum of two rational numbers is -7. If one of the numbers is –15/19, the other number is

Answer 1

Let the other number be x.

Given

$\bold{One \ of \ the \ numbers} = \dfrac{-15}{19}$

$\bold{Sum \ of \ two \ rational \ numbers} = -7$

$\implies x + \dfrac{-15}{19}=-7$

$\implies x = -7+\dfrac{15}{19}$

$\implies x = \dfrac{-133+15}{19}$

$\implies x = \dfrac{-118}{19}$

$\boxed{\boxed{\bold{Therefore, \ the \ other \ number \ is \ \dfrac{-118}{19}}}}}}}}$

                                                       

Answer 2

Given,

$\tt One \ of \ the \ numbers = \dfrac{-15}{19}$

$\tt Sum \ of \ the \ numbers = -7$

Let the required Number be x

A/q

$\tt \implies x + \dfrac{ - 15}{ 19} = - 7$

$\tt \implies x = - 7 - ( \dfrac{ - 15}{19} )$

$\tt \implies x = \dfrac{ - 7}{1} + \dfrac{15}{19}$

$\tt \implies x = \dfrac{ - 133 + 15}{19}$

$\tt \implies x = \dfrac{-118}{19}$

Therefore, The Required number is $\sf \dfrac{-118}{19}$

Additional Information

• If a number contains one term, it is said to be as Monomial.

• If a number contains two non-zero term, it is said to be as Binomial.

• If a number contains three non-zero term, it is said to be as Trinomial.

• $\sf HCF \times LCM = PRODUCT$
