Which expression is equivalent to 16.8-18.6 ? Choose 1 answer: (A) 18.6-16.8 (B) -18.6+(-16.8) (C) 16.8-(-18.6) (D) 16.8+(-18.6)

Perform Subtraction: We need to find an expression that is equivalent to the subtraction of two numbers, 16.8 and 18.6. Let's start by performing the subtraction to understand what we are looking for. 16.8 - 18.6 = -1.8 We are looking for an expression that also results in -1.8.Evaluate Option (A): Let's evaluate option (A) 18.6 - 16.8. 18.6 - 16.8 = 1.8 This is not equivalent to -1.8, so option (A) is not correct.Evaluate Option (B): Now let's evaluate option (B) -18.6 + (-16.8). -18.6 + (-16.8) = -18.6 - 16.8 = -35.4 This is not equivalent to -1.8, so option (B) is not correct.Evaluate Option (C): Next, let's evaluate option (C) 16.8 - (-18.6). 16.8 - (-18.6) = 16.8 + 18.6 = 35.4 This is not equivalent to -1.8, so option (C) is not correct.Evaluate Option (D): Finally, let's evaluate option (D) 16.8 + (-18.6). 16.8 + (-18.6) = 16.8 - 18.6 = -1.8 This is equivalent to the original expression 16.8 - 18.6, so option (D) is correct.

Perform Subtraction: We need to find an expression that is equivalent to the subtraction of two numbers, $16.8$ and $18.6$ . Let's start by performing the subtraction to understand what we are looking for. $\newline$ $16.8 - 18.6 = -1.8$ $\newline$ We are looking for an expression that also results in $-1.8$ .
Evaluate Option (A): Let's evaluate option (A) $18.6 - 16.8$ . $\newline$ $18.6 - 16.8 = 1.8$ $\newline$ This is not equivalent to $-1.8$ , so option (A) is not correct.
Evaluate Option (B): Now let's evaluate option (B) $-18.6 + (-16.8)$ . $-18.6 + (-16.8) = -18.6 - 16.8 = -35.4$ This is not equivalent to $-1.8$ , so option (B) is not correct.
Evaluate Option (C): Next, let's evaluate option (C) $16.8 - (-18.6)$ . $\newline$ $16.8 - (-18.6) = 16.8 + 18.6 = 35.4$ $\newline$ This is not equivalent to $-1.8$ , so option (C) is not correct.
Evaluate Option (D): Finally, let's evaluate option (D) $16.8 + (-18.6)$ . $\newline$ $16.8 + (-18.6) = 16.8 - 18.6 = -1.8$ $\newline$ This is equivalent to the original expression $16.8 - 18.6$ , so option (D) is correct.
