D 3.4
To evaluate the numerical expression 4.2 − 3.5 ÷ 0.7 + 2.4, we follow the order of operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right)).
First, we perform the division 3.5 ÷ 0.7 = 5.
Then, we substitute this result into the expression, giving us 4.2 − 5 + 2.4.
Next, we perform the subtraction 4.2 − 5 = -0.8.
Finally, we perform the addition -0.8 + 2.4 = 1.6.
So the numerical expression evaluates to 1.6.
Therefore, the answer is B) 1.6.
