Answer 1

Answer:

$\frac{ - 19}{10} \\ or \\ - 1.9$

Step-by-step explanation:

Let x be the number which is added to 2/5 to get -3/2

So,

$\frac{2}{5} + x = \frac{ - 3}{2} \\ \frac{2 + 5x}{5} = \frac{ - 3 }{2} \\ cross \: multiplying \\ 2(2 + 5x) = 5( - 3) \\ 4 + 10x = - 15$

$10x = - 15 - 4 \\ 10x = - 19 \\ x = \frac{ - 19}{10} \\ or \\ x = - 1.9$
