What is 2.8 as a fraction?

2.8 can be written as a fraction in several ways depending on the desired form.

One way is to write it as a mixed number, which combines a whole number and a fraction. In this case, 2.8 can be written as:

2 4/5

This means that 2 units are combined with 4/5 of another unit.

Another way to write 2.8 as a fraction is to convert it to an improper fraction, which has a numerator greater than the denominator. To do this, we multiply the whole number by the denominator and add the result to the numerator. Then, we keep the same denominator.

2.8 = 2 + 0.8 (since 0.8 is the decimal part of 2.8) = 2 + 8/10 (since 0.8 = 8/10) = 2 8/10

Then, we simplify this fraction by dividing the numerator and the denominator by their greatest common factor, which is 2 in this case.

2 8/10 = (2 x 2 + 8)/ (10 x 2) = 12/5

Therefore, 2.8 can be written as 2 4/5 or 12/5.
