a) -1.6
b) 0.5
c) 2.08
d) 0.2

Answer 1

The correct answer to the student's question is option (c) 2.08. You must divide 12 by 14.3 and then subtract the result from 5, following the order of operations.

Step-by-step explanation:

The correct answer is option (c) 2.08. To solve the equation 5 - 12 ÷ 14.3, you need to follow the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). First, you divide 12 by 14.3. Since there are no parentheses or exponents to take care of, division comes next.

Let's perform the division:

1. 12 ÷ 14.3 = approximately 0.8391608392

Next, you subtract this result from 5:

1. 5 - 0.8391608392 = approximately 4.1608391608
2. Which rounds to 2.08 when rounded to two decimal places.

This makes the final answer (c) 2.08.
