Answer:
3:5 and 50:100
Step-by-step explanation:
You could re-write ratios as fractions.
The first one is 16/20 which is the exact same as 8/10 so that isn't possible.
The second one is 3/5. We can find a common denominator for both of the fractions which is 10 so 3/5 = 6/10 which means 3/5 is less than 8/10.
The 3rd one is 50/100 which can also be written as 5/10 which is less than 8/10.
The 4th one is 13/15. 8/10 can also be written as 12/15. Since 13 is bigger than 12 that is not correct.
This means that the 2nd and 3rd one are correct.
Hope this Helps!!! :)
