This worksheet would be a great accompaniment to Percentages of Amounts (A), (B) and (C), as well as the Spider Percentages worksheets.

Section A asks students to complete a table asking for simple percentages such as 10%, 50%, and 20% that can be found mentally. The last column of the table is a little more challenging by asking those percentages to be found from a decimal value.

Section B is a set of questions that can all be found using mental methods. This section could be used as a timed challenge.
