Hi Kristin,
 
What you want to do is set up a whole fraction by multiplying the denominator (5) by 2 = 10, and then adding the numerator (4) = 14. You then put 14 as the numerator and keep 5 as the denominator. You then can set up the equation used to find percentage. 14/5 = x/100.
 
Cross multiplying, you end up with 1400 = 5x.
 
Dividing both sides by 5, solving for x gives you 280. Therefore x = 280 and your answer is 280%
 
Thanks and I hope that helps.
 
David

Hi Kristin;
2 4/5
2 is 200%.  We must add this to the result of 4/5.
Let's take 4/5 and multiply the top number (numerator) by 20, while multiplying the bottom number (denominator) by 20...
[(4)(20)]/[(5)(20)]
80/100
80%
80%+200%=280%

"convert 2 and 4/5 to a percent"
 
(2 and 4/5) = (2 + 4/5)*100/100 = (200 + 80)/100 = 280 %
