Which is the form of -7/3 with the opposite sign?

Answer and explanation

Correct answer: 7/3

The governing concept is the additive inverse of a rational number. The opposite-sign form of a number x is -x, and x plus -x equals zero. Here x = -7/3, so its opposite is -(-7/3) = 7/3. The check is (-7/3) + (7/3) = 0, confirming that option A is correct. Option B is the reciprocal of -7/3, not its additive inverse. Option C is the reciprocal of the positive value 7/3. Option D has two negative signs, so it simplifies to 7/3 and represents the same value, but option A is the standard and clearest form requested. The key distinction is between changing a sign and taking a reciprocal.
