Answer

$\boxed{8}$ is 1\% of Dan's number

Steps

Step 1 ：Given that 20\% of Dan's number is 160, we can set up an equation: $0.20 * x = 160$

Step 2 ：Solve for x: $x = \frac{160}{0.20} = 800$

Step 3 ：Now, we need to find 1\% of Dan's number: $0.01 * 800 = 8$

Step 4 ：$\boxed{8}$ is 1\% of Dan's number
