Using the place value chart, we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction \frac{4}{10}. Notice however that the fraction is not in lowest terms. We will need to divide the numerator and the denominator by the greatest common factor of 4 and 10 which is 2. Therefore, 0.4 can be written as the fraction \frac{2}{5}, which is in lowest terms.

Hello!

<em><u>Answer: ⇒ 27/20</u></em>

Step-by-step explanation:

Since the denominators are equal, then combine the fractions.

\frac{8+5+14}{20}

Add by the numbers.

8+5+14=27

=\frac{27}{20}

Hope this helps!
