Let's break down and solve the expression step by step:

Expression:  
\[
2.20 \times 0.75 + \frac{3}{5} \div \frac{1}{8}
\]

### Step 1: Simplify the multiplication part
\[
2.20 \times 0.75 = 1.65
\]

### Step 2: Simplify the division part
\[
\frac{3}{5} \div \frac{1}{8} = \frac{3}{5} \times \frac{8}{1} = \frac{24}{5} = 4.8
\]

### Step 3: Add the results
