2.4 x 0.8

Step 1: Convert the numbers to fractions.
2.4 = \frac{24}{10} = \frac{12}{5}
0.8 = \frac{8}{10} = \frac{4}{5}

Step 2: Multiply the fractions.
\frac{12}{5} \times \frac{4}{5} = \frac{12 \times 4}{5 \times 5} = \frac{48}{25}

Step 3: Convert the result back to a decimal.
\frac{48}{25} = 1.92

Therefore, the answer is 1.92.
