How do you write 280% as a fraction or mixed number in simplest form?

For this case, what you need to know is that you have a number in the form of a percentage.
 To write it as a number you must divide this value by 100.
 We have then:
 (280%) / (100%) = 2.8
 Equivalently in the form of fraction we have:
 2.8 = (28) / (10)
 2.8 = 14/5
 
 280% as a fraction or mixed number in simplest form is:
 14/5
 or
 2.8
