Answer 2

To calculate the expression "2 + 5 * 2 - 5 / 8," you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

In your expression, there are no parentheses or exponents, so you proceed with multiplication and division from left to right, and then addition and subtraction from left to right:

1. 5 * 2 = 10
2. 5 / 8 = 5/8

Now, you have:

2 + 10 - 5/8

Next, perform addition and subtraction:

2 + 10 = 12

So, the expression becomes:

12 - 5/8

To subtract fractions, you need a common denominator, which in this case is 8. So, rewrite 12 as an equivalent fraction with a denominator of 8:

12 = 96/8

Now, subtract the fractions:

96/8 - 5/8 = (96 - 5) / 8 = 91/8

So, the result is 91/8, which is equivalent to 11.375 when expressed as a decimal.

So, the answer is not one of the options (A) 1/4, (B) 1/2, (C) 4, or (D) 2. The correct answer is 91/8, or 11.375 as a decimal.
