The only pair of fractions that is equivalent is 18/27 and 10/15. Option B is correct.
To find which fractions are comparable, let's compare each pair:
12/20 and 20/25:
Simplify each fraction:
12/20 = 3/5
20/25 = 4/5
Since 3/5 and 4/5 are not equal, these fractions are not equivalent.
18/27 and 10/15:
Simplify each fraction:
18/27 = 2/3
10/15 = 2/3
Since 2/3 and 2/3 are equal, these fractions are equivalent.
6/24 and 5/15:
Simplify each fraction:
6/24 = 1/4
5/15 = 1/3
Since 1/4 and 1/3 are not equal, these fractions are not equivalent.
3/25 and 5/25:
Simplify each fraction:
3/25 = 3/25
5/25 = 5/25
Since 3/25 and 5/25 are equal, these fractions are equivalent.
So, the only pair of fractions that is equivalent is 18/27 and 10/15
