Evaluate the numerical expression:

\[ 7.5 \times 6.6 \div 0.6 - 15.3 \]

A) -32.25
B) 67.2
C) 97.8
D) 197.25

Answer :

Final answer:

The numerical expression is solved by following the order of operations (PEMDAS), resulting in the correct answer of B) 67.2

Explanation:

Firstly, you need to follow the order of operations which is commonly known by the acronym PEMDAS: Parentheses first, Exponents (ie Powers and Square Roots, etc.), Multiplication and Division (left-to-right), Addition and Subtraction (left-to-right). This numerical expression contains no parentheses, exponents, addition or subtraction, so we'll first perform the multiplication and division from left to right.

The multiplication step is: 7.5 × 6.6 = 49.5

Next, this result is divided by 0.6:

Next step is: 49.5 ÷ 0.6 = 82.5

Finally, we subtract 15.3 from this result:

The Final step is: 82.5 - 15.3 = 67.2

Therefore, the evaluation of the numerical expression 7.5 × 6.6 ÷ 0.6 − 15.3 gives the result 67.2. Consequently, the correct answer is B) 67.2
