The sum of two rational numbers is -3. If one of them is -5/2 the other will be

Answer 1

Step-by-step explanation:

Let the rational number be x

a/q,

$x + ( \frac{ - 5}{2} ) = - 3$

$x - \frac{5}{2} = - 3$

$x = - 3 + \frac{5}{2}$

$x = \frac{ - 3 \times 2 + 5}{2}$

$x = \frac{ - 6 + 5}{2}$

$x = \frac{ - 1}{2}$

hence, the rational number is -1/2

Answer 2
