Understand the Problem: Understand the problem. We need to find an expression that is equivalent to the subtraction of two numbers, 16.8 and 18.6.Analyze the Choices: Analyze the given choices. (A) 18.6 - 16.8 is the reverse subtraction, which will give a positive result. (B) -18.6 + (-16.8) is adding two negative numbers, which will result in a more negative number. (C) 16.8 - (-18.6) is subtracting a negative number from a positive number, which is the same as adding the absolute values of both numbers. (D) 16.8 + (-18.6) is adding a negative number to a positive number, which is the same as subtracting the absolute value of the negative number from the positive number.Calculate the Expression: Calculate the original expression. 16.8 - 18.6 = -1.8 This is because when we subtract a larger number from a smaller number, we get a negative result.Match with Choices: Match the result with the choices. We are looking for an expression that also results in -1.8. (A) 18.6 - 16.8 = 1.8 (This is positive, so it's not equivalent.) (B) -18.6 + (-16.8) = -35.4 (This is more negative, so it's not equivalent.) (C) 16.8 - (-18.6) = 16.8 + 18.6 = 35.4 (This is positive and larger, so it's not equivalent.) (D) 16.8 + (-18.6) = 16.8 - 18.6 = -1.8 (This matches our original calculation.)

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