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 Answer: 280% as a fraction or mixed number in simplest form is: 14/5 or 2.8
