To convert 12.8 to a fraction, follow these steps:
-
Start by expressing the decimal as a fraction: \[ 12.8 = \frac{128}{10} \]
-
Simplify the fraction:
- Find the greatest common divisor (GCD) of 128 and 10. The GCD is 2.
- Divide both the numerator and denominator by their GCD: \[ \frac{128 \div 2}{10 \div 2} = \frac{64}{5} \]
Thus, the simplest form of 12.8 as a fraction is: \[ \frac{64}{5} \]
However, if we specifically look at the provided answers, we notice:
- 12 Start Fraction 4 over 5 End Fraction can be interpreted as \(12 + \frac{4}{5} = 12.8\).
Hence, if the options were meant to match the whole number and the fraction, the answer would be: \[ 12 \frac{4}{5} \]
Therefore, the correct answer is \( \text{12} \frac{4}{5} \).
