What is the decimal opposite of −3 3/4?

Explanation:
The decimal opposite is the additive inverse—the number with the opposite sign that would bring you back to zero when added. First convert the mixed number -3 3/4 to decimal: 3/4 is 0.75, so -3 3/4 is -3.75. The opposite of -3.75 is +3.75, which is 3.75 in decimal form. So the best answer is 3.75. The other options are either the wrong sign or have a different magnitude (for example, -3.75 would not undo the original amount, and 4.0 or -4.0 have magnitudes not equal to 3.75).
