Correct Answer
B. 6/144, 1/8, 3/12, 8/14, 19/18Explanation
The fractions are ordered from least to greatest based on their decimal equivalents. To compare fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 144. We convert each fraction to its equivalent with a denominator of 144 and then compare the numerators. The fractions with the smaller numerators are placed first, while the fractions with larger numerators are placed later. Therefore, the correct order from least to greatest is 6/144, 1/8, 3/12, 8/14, 19/18.Rate this question:
