0. This can be represented as: $20\% \times 1800$.

2. Solution Steps

First, we convert the percentage to a decimal by dividing by 100:

$20\% = \frac{20}{100} = 0.20 = 0.2$.

Next, we multiply the decimal by 1,800:

$0.2 \times 1800$.

We can also write $1800$ as $18 \times 100$.

So, $0.2 \times 1800 = 0.2 \times (18 \times 100) = (0.2 \times 18) \times 100$.

$0.2 \times 18 = 3.6$.

Then, $3.6 \times 100 = 360$.

Alternatively,

$\frac{20}{100} \times 1800 = \frac{20 \times 1800}{100} = \frac{36000}{100} = 360$.

3. Final Answer

360
