Question

Explain how to use a horizontal number line
to order four fractions from least to greatest.

Answer 1

To order fractions from least to greatest, start by finding the lowest common denominator for all of the fractions. Next, convert each of the fractions by dividing the lowest common denominator by the denominator and then multiplying the top and bottom of the fraction by your answer.

Explanation:

Solution for the above problem: We first find the least common denominator by finding the least common multiple for 4, 3, 2, 6, and 8. We find the LCM by the prime factorization method. Next, place the fractions in order from least to greatest.

Answer 2

Sample Response: Plot each fraction on a number line. Note any fractions that are equivalent. The fractions located on the left are the lesser, and the fractions on the right are greater. Write the fractions beginning from the farthest left to the farthest right, and they will be ordered from least to greatest.
