To convert 12.8 to a fraction, first express it as:
\[ 12.8 = 12 + 0.8 \]
Next, convert \( 0.8 \) to a fraction. The decimal \( 0.8 \) can be written as:
\[ 0.8 = \frac{8}{10} \]
Now, simplify \( \frac{8}{10} \) by dividing both the numerator and the denominator by their greatest common divisor (which is 2):
\[ \frac{8 \div 2}{10 \div 2} = \frac{4}{5} \]
Now, combine the whole number and fraction:
\[ 12 + \frac{4}{5} = \frac{12 \cdot 5}{5} + \frac{4}{5} = \frac{60}{5} + \frac{4}{5} = \frac{64}{5} \]
Thus, 12.8 as a fraction in simplest form is:
\[ \frac{64}{5} \]
