Answer:
0
Explanation:
If the answer is between 0 to 0.49, the best estimate is 0.
If the answer is between 0.5-1.49, the best estimate is 1.
If the answer is 1.5 or greater, the best estimate is 2.
Without giving the fractions 1/10 and 1/12 a common denominator, we know the answer is between 2/12 and 2/10.
2/12 is less than 2/10. 2/10 is 0.2, which is less than 0.5.
Since the final answer is less than 0.5, the best estimate is 0.
