9514 1404 393

Answer:

6/20, 3:5, 50/100 are all less than 8/10

Explanation:

It can help to give all the ratios a common denominator. (We'll use 100, and fudge the last one a bit.)

8/10 = 80/100 . . . . our reference value

__

6/20 = 30/100 . . . less than 8/10

3/5 = 60/100 . . . . less than 8/10

50/100 . . . . . . . . . less than 8/10

13/15 ≈ 86.7/100 . . . more than 8/10
