A tomato is cut into 8 slices. If each slice contains 0.12 grams of fiber, how can rounding be used to estimate the amount of fiber in the entire tomato?
A: Since the slices have about 0.20 grams of fiber each, the amount of fiber in the entire tomato is approximately 8 x 0.20 = 1.60 grams.
B: Since the slices have about 0.20 grams of fiber each, the amount of fiber in the entire tomato is approximately 8 + 0.20 = 8.20 grams.
C: Since the slices have about 0.10 grams of fiber each, the amount of fiber in the entire tomato is approximately 8 x 0.10 = 0.80 grams.
D: Since the slices have about 0.10 grams of fiber each, the amount of fiber in entire tomato is approximately 8 + 0.10 = 8.10 grams.
