Answer 1

To multiply $-2\frac{1}{2}$ by $-1\frac{3}{5}$, first convert them to improper fractions.

1. Convert $-2\frac{1}{2}$: $$-2\frac{1}{2}=-(2\times 2+1)/2=-\frac{5}{2}$$

2. Convert $-1\frac{3}{5}$: $$-1\frac{3}{5}=-(1\times 5+3)/5=-\frac{8}{5}$$

Now multiply the two improper fractions together: $$(-\frac{5}{2})\times (-\frac{8}{5})=\frac{5\times 8}{2\times 5}=\frac{40}{10}=4$$

Now, convert $4$ to decimal: $$4.0$$

Thus, the answer is: 4.0
