Which is greater, 4/5 or 75%?*

4/5. 4/5 is equal to 80%

Step-by-step explanation:

4/5

Step-by-step explanation:

4/5 is equal to 80%, which is more than 75%.  How you can figure this out is that you can determine 4/5 of 100, (divide 100 by 5 and pick the 4th part,) to get 80.  75% is equal to 3/4, so divide 100 by 4 and shoose the 3rd part, 75.  Therefore, 4/5 is greater than 75%.  

Hope this helps!  :)
