# 3.8 as a Fraction

Here you can find 3.8 as a fraction, both as decimal fraction and in simplest form. We show you how to convert 3.8 to a fraction using the step by step instructions which can be found on our home page. There, you can also learn all about the others terms used in this article. If you have been looking for 3.8 in fraction form or 3.8 repeating as a fraction, then you are right here, too.

3.8 has 1 decimal place, so we put the decimal digit of 3.8, 8, over 1 followed by the number of zeroes equal to the number of decimal places, 1: 8 = 8/10. We add 3 as 30/10 and get:

3.8 as decimal fraction = 38/10

38 is the nominator and 10 is the denominator. We now check if the decimal fraction is already in the lowest terms by finding the greatest common factor of 38 and 10, know as gcf of 38 and 10.

The gcf(38,10) is 2, so we can conclude that 38/10 is not 3.8 as a fraction in simplest form. To obtain 3.8 as a fraction in simplest form we have to divide both, the nominator as well as denominator, by the gcf(38,10):

38/10 = $\frac{\frac{38}{gcf(38,10)}}{\frac{10}{gcf(38,10)}}$ = $\frac{\frac{38}{2}}{\frac{10}{2}}$ = $\frac{19}{5}$

We write 3.8 as a fraction in simplest form as 19/5.

3.8 as a fraction in its lowest terms is 19/5

## What is 3.8 as a Fraction

We have already answered what is 3.8 as a fraction above for the cases 3.8 as decimal fraction and 3.8 as a fraction in simplest form.

Yet, by multiplying the denominator and the nominator of 3.8 as a fraction in simplest form with all integers distinct from zero and one we can generate an infinite amount of fractions equivalent to 19/5, but not in lowest terms:

19/5 = $\frac{n\hspace{3px} x\hspace{3px} 19}{n\hspace{3px} x\hspace{3px} 5}$ $\hspace{3px} n \hspace{3px}\epsilon\hspace{3px}\mathbb{Z},\hspace{3px} n\neq 0$.

For example, with n = 2 we obtain 38/10 and with n = -3 we get 57/15:
38/10 = 57/15 = 19/5.

We can thus conclude that the question What is 3.8 as a fraction? does not have a single answer, but an indefinite amount of possibilities.

## 3.8 Repeating as a Fraction

To find out what is 3.8… as a fraction, identify the repeating sequence or pattern, known as reptend or repetend of 3.8 recurring.

The infinitely-repeated digit sequence of 3.8… can be indicated by three periods. For example, 3.888… as a fraction (repeating 8, the last digit) = 3 8/9 .

Alternatively, a vinculum, that is a horizontal line, can be drawn above the repetend of the fraction of 3.8. In addition, one can sometimes see the period enclosed in parentheses ().

Here, we use the overlined notation to denote 3.8 repeating as a fraction:

3.8 =3 8/9
