how do I write 2.8 as a fraction?
Well you see, you have 2/8, (fraction) and here is a few others,
These are COMMON. 4/16, 2/8, 6/24, etc....
You multiply the denominator and numerator by the same answer.
Thats how I think I learned it.
2.8 = \(2 \frac{8}{10}\)=2\(\frac{4}{5}}\)=14/5. Therefore, 2.8 as a fraction would be \(\boxed{{\frac{14}{5}}}}}}}\). Hoped I helped. :)
