Ineed to find the overall answer and explanation of how to get it

Okay this one is simple once when you get an understanding of what they are asking. First divide the numerators by the denominators. 2/5=0.4 this is terminating because there are no numbers after it ends at 4. 7/45 is 0.15555556... this is repeating because it keeps on going. 5/99 is 0.05050505... repeating. Lastly 27/250 is 0.108 this is terminating because it stops. :) Hope this helps.
