Answer 2

a) 7/9 and 11/27 To compare these fractions, we can find a common denominator. The least common multiple of 9 and 27 is 27. We can then rewrite the fractions with the common denominator: 7/9 = 21/27 11/27 = 11/27 Now we can compare them: 21/27 > 11/27

b) 3/40 and 11/20 To compare these fractions, we can find a common denominator. The least common multiple of 40 and 20 is 40. We can then rewrite the fractions with the common denominator: 3/40 = 3/40 11/20 = 22/40 Now we can compare them: 3/40 < 22/40

c) 3/5 and 5/7 To compare these fractions, we can find a common denominator. The least common multiple of 5 and 7 is 35. We can then rewrite the fractions with the common denominator: 3/5 = 21/35 5/7 = 25/35 Now we can compare them: 21/35 < 25/35

d) 2/3 and 4/15 To compare these fractions, we can find a common denominator. The least common multiple of 3 and 15 is 15. We can then rewrite the fractions with the common denominator: 2/3 = 10/15 4/15 = 4/15 Now we can compare them: 10/15 > 4/15

In summary, when comparing the given fractions: a) 7/9 > 11/27 b) 3/40 < 11/20 c) 3/5 < 5/7 d) 2/3 > 4/15
