First, let's simplify the expressions inside the parentheses:

-4\7\12 + 6\3\4 = -4/7 (12) + 6/3 4
= -48/7 + 24/3
= -48/7 + 8
= -48/7 + 56/7
= 8/7

Now let's calculate the first expression:

0.04 (8/7) = 0.04 8/7
= 0.32/7
= 0.0457

Now let's calculate the second expression:

-0.56 - 0.02 * 0.44 = -0.56 - 0.0088
= -0.5688

Therefore, the final answer is:

0.04 (-4/7 + 6/4) = 0.0457; 0.02 (-0.56) - 0.02 * 0.44 = -0.5688
