Math worksheet for calculating percentages of numbers, including a rhino illustration.

Let's solve each problem step by step. To find a percentage of a number, we use the formula:

$$
\text{Percentage of a number} = \left( \frac{\text{Percent}}{100} \right) \times \text{Number}
$$

We'll calculate each one and round to the nearest hundredth (i.e., two decimal places).
