Calculate the expression:

\[ 8.8 + \left(\frac{1}{5} \times 5 + 2.6\right) \]

Choose the correct answer:

A. 7.1
B. 39.1
C. 12.4
D. 16.3

Answer :

Final answer:

To find the solution, operations inside the parenthesis are executed first, resulting in 3.6, which when added to 8.8 gives the final answer of 12.4 (option C).

Explanation:

To solve the expression 8.8 + ( 1/5 × 5 + 2.6), first, we need to perform the operations inside the parenthesis. This is following the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Inside the parenthesis, we have 1/5 × 5 + 2.6. Multiplication comes before addition, so we'll do that first:

1/5 × 5 = 1

Next, we add the result to 2.6:

1 + 2.6 = 3.6

Now we can add this result to 8.8:

8.8 + 3.6 = 12.4

Thus, the correct answer is 12.4, which corresponds to option C.
