Using the rule of BODMAS, solve the problems below: 1/2 of 120 divided by (1/5 of 100)

The "of" operation means multiplication.
Calculate $\frac{1}{5} \text{ of } 100$:

$$\frac{1}{5} \times 100 = \frac{100}{5} = 20$$

The expression becomes:

$$\frac{1}{2} \text{ of } 120 \div 20$$

Calculate $\frac{1}{2} \text{ of } 120$:

$$\frac{1}{2} \times 120 = \frac{120}{2} = 60$$

The expression becomes:

$$60 \div 20$$

$$60 \div 20 = 3$$

The final answer is:

$$3$$
