Answer 3

To solve the expression (49 - 78 - 0.1) / (3.12 + 0.88), we follow the order of operations, which is typically represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, let's simplify the expression within the parentheses:

49 - 78 - 0.1 = -28.1

Next, we'll simplify the expression in the denominator:

3.12 + 0.88 = 4

Now, we can substitute the simplified values back into the original expression:

(-28.1) / 4 = -7.025

Therefore, the result of the expression (49 - 78 - 0.1) / (3.12 + 0.88) is -7.025.
