Which of the following is the decimal result of adding 3 7/8, 2 5/8, and 3/16?

Explanation:
Adding mixed numbers and fractions works best when everything is in the same form so the parts line up. Convert each term to decimals, then add. 3 7/8 is 3.875, 2 5/8 is 2.625, and 3/16 is 0.1875. Add the whole parts: 3 + 2 = 5. Then add the fractions: 0.875 + 0.625 + 0.1875 = 1.6875. Combine to get 5 + 1.6875 = 6.6875. So the total in decimal form is 6.6875, which is 6 11/16 in fractional form. None of the listed options matches 6.6875. To check quickly with fractions: 3 7/8 + 2 5/8 = 6 1/2, then plus 3/16 gives 6 11/16.
