$c) \$\\frac{10}{6} \\cdot 0.6\$$

c) \$\frac{10}{6} \cdot 0.6\$

0.6 can be written as $\frac{6}{10}$ (or simplified as $\frac{3}{5}$). So the expression becomes $\frac{10}{6} \cdot \frac{6}{10}$.

When multiplying fractions, we multiply the numerators together and the denominators together: $\frac{10 \times 6}{6 \times 10}$.

The numerator is $10\times6 = 60$ and the denominator is $6\times10 = 60$. So $\frac{60}{60}=1$.
