Question

Which set of fractions is ordered from greatest to least 2/3,3/8,5/12 b) 5/12, 3/8, 2/8

Answer 1

Answer:

B

Explanation:

To determine which fraction is bigger, we need to get every fraction under the same denominator.  

In set A, 3, 8 and 5 have an LCM of 24

So we multiply (which we can because 8/8 = 1, 3/3 = 1, etc.)

2/3 times 8/8 -> 16/24

3/8 times 3/3 -> 9/24

and

5/12 times 2/2 -> 10/24

Since 10 > 9 but 9 comes before 10 in the set, A cannot be the answer, so B is.
