B.
`-(7)/(10)` = -.7

Explanation:

Replace all occurrences of − − with a single +. Two consecutive minus signs have the same mathematical meaning

Find the common denominator.

`(-.75*20)/(20) +(2*4)/(20) +(.4*20)/(20)-(3*5)/(20)`

Simplify terms.

`(-15+8+8-15)/(20)`

Simplify the numerator.

`(-14)/(20)`

Reduce the expression by cancelling the common factors.

`-(7)/(10)`

hope this helps, good luck :)
