We will solve the expression step by step:

The expression is:

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

### Step 1: Simplify \(2.20 \times 0.75\)
\[
2.20 \times 0.75 = 1.65
\]

### Step 2: Simplify \(\frac{3}{5} \div \frac{1}{8}\)
When dividing fractions, we multiply by the reciprocal. So:

\[
\frac{3}{5} \div \frac{1}{8} = \frac{3}{5} \times \frac{8}{1} = \frac{3 \times 8}{5 \times 1} = \frac{24}{5} = 4.8
\]

### Step 3: Combine the results
Now we add the two results together:

\[
1.65 + 4.8 = 6.45
\]

So, the value of the expression is **6.45**.
