1r. Snow loves his coffee. He fills up a cup \( 8 / 10 \) full. He drinks \( 2 / 5 \) of his Arink. How much does he have left?

To find how much coffee Snow has left, we start with the amount he fills his cup: \( \frac{8}{10} \). Snow drinks \( \frac{2}{5} \) of his drink. To perform the calculation, we first convert \( \frac{2}{5} \) into a fraction with a denominator of 10 for easier subtraction. Since \( \frac{2}{5} = \frac{4}{10} \), he drinks \( \frac{4}{10} \) of his drink. Now we subtract the amount he drank from the amount he originally had: \[ \frac{8}{10} - \frac{4}{10} = \frac{4}{10} \] To simplify \( \frac{4}{10} \), we can divide both the numerator and the denominator by 2: \[ \frac{4 \div 2}{10 \div 2} = \frac{2}{5} \] Therefore, Snow has \( \frac{2}{5} \) of his coffee left.
