Well since it's better to teach you than answer, I'll give you an explanation using #1.

6.88

Step-by-step explanation:

In the parentheses, 1.6 has one decimal place, and so does 4.3. (count number of digits after decimal point.) So a total of 2 decimal places. (1) + (1) = (2)

Next, ignore the decimal points for now and multiply 16 × 43 = 688.
