Answer:

B. $-\frac{7}{10}$ = -.7

Step-by-step explanation:

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

$-.75+\frac{2}{5}+.4-\frac{3}{4}$

Find the common denominator.

$\frac{-.75*20}{20} +\frac{2*4}{20} +\frac{.4*20}{20}-\frac{3*5}{20}$

Simplify terms.

$\frac{-15+8+8-15}{20}$

Simplify the numerator.

$\frac{-14}{20}$

Reduce the expression by cancelling the common factors.

$-\frac{7}{10}$

<em>hope this helps, good luck :)</em>
