0. The question asks for 1% of Zachary's number.

2. Solution Steps

Let $x$ be Zachary's number. We are given that 20% of $x$ is

1

8

0. We can write this as:

$0.20x = 180$

To find $x$, divide both sides by 0.20:

$x = \frac{180}{0.20} = \frac{180}{\frac{2}{10}} = \frac{180 \times 10}{2} = \frac{1800}{2} = 900$

So, Zachary's number is

9

0

0. Now, we want to find 1% of Zachary's number, which is 1% of

9

0

0. $1\%\ \text{of}\ 900 = 0.01 \times 900 = \frac{1}{100} \times 900 = 9$

3. Final Answer
