Final answer:
To compare the fractions 6/10 and 4/6, convert both fractions to have the same denominator and compare the numerators. The fraction 4/6 is greater than 6/10.
Step-by-step explanation:
To compare the fractions 6/10 and 4/6, we can convert both fractions to have the same denominator. The least common multiple of 10 and 6 is 30. Therefore, to compare the fractions, we need to convert them to fractions with a denominator of 30.
Converting 6/10 to have a denominator of 30, we multiply both the numerator and denominator by 3, resulting in 18/30.
Converting 4/6 to have a denominator of 30, we multiply both the numerator and denominator by 5, resulting in 20/30.
Now that both fractions have the same denominator, we can compare the numerators. Since 20 is larger than 18, the fraction 4/6 is greater than 6/10.
Therefore, the correct phrase to insert on the line is: a. Is greater than.
