Question

By what number should we multiply (-15)/2 ,so that product may be (-5)/7 ?

Answer 1

Given

$\bold{One \ of \ the \ numbers} = \dfrac{-15}{2}$

$\bold{Product \ of \ the \ numbers} = \dfrac{-5}{7}$

Let the other number be x.

$\implies \dfrac{-15}{2} \times x = \dfrac{-5}{7}$

$\implies x = \dfrac{-5}{7} \times \dfrac{2}{-15}$

$\implies x = \dfrac{2}{21}$

$\boxed{\boxed{\bold{Therefore, \ the \ other \ number \ is \ \dfrac{2}{21}}}}}}}$

                                                                       

Answer 2

By what number should we multiply (-15)/2 ,so that product may be (-5)/7 ?

Solution :-

$\sf$

• Let the number be = x

$\sf$

★ According To Question ★

→ -5/7*x = -15/2

→ x = -5/7×-2/15

→ x = 10/35

→ x = 2/21

Hence :-

The number is 2/21
