Answer:
75%
Step-by-Step Explanation:
There are two ways to go about this.
1) We can simply put it as a fraction = 60/80.
   Then since a fraction sign also means division, we divide 60 by 80 = 0.75
   Then to change a decimal into a percentage, we multiply by 100% = 75%
   So our answer is 75%
2) We can simply it after it is put into a fraction = 60/80 = 3/4
    It should be common knowledge that 3/4 is 75% depending on what                 grade you are in.
But there you have it, whichever way you prefer, the answer is always 75%.
