To solve this, we need to perform the operations in the correct order of operations (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right).

First, we simplify the expression (-12/5 - 3/4) by finding a common denominator:
(-12/5 - 3/4) = (-48/20 - 15/20) = -63/20

Next, we simplify the expression (3/1 + 5.3/1) by adding the fractions and decimals together:
(3/1 + 5.3/1) = (3 + 5.3) = 8.3

Finally, we multiply 8.3 by 0.75:
8.3 * 0.75 = 6.225

Therefore, the final result is:
-63/20 and 6.225
