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.
