Worksheet for finding a specified percent of a given number, organized into three sections: benchmark percents (10%, 25%, 50%, 75%, 100%), common percents (15%, 20%, 30%, 40%, 60%), and challenge percents (35%, 45%, 65%, 80%). Each problem asks for the percent-of relationship, showing work using decimal equivalents (e.g., 0.10, 0.25) and multiplication. An added word problem uses a budget scenario to compute spending amounts and savings, including a final percent of what is saved. Answer key solutions are provided for all items.

FAQs

How do you find a percent of a number on this worksheet?

Convert the percent to a decimal (for example, 10% = 0.10) and multiply by the number.

What percent groups are covered in Section 1 and Section 2?

Section 1 uses benchmark percents (10%, 25%, 50%, 75%, 100%), and Section 2 uses common percents (15%, 20%, 30%, 40%, 60%).

How is the challenge problem solved?

Compute amounts spent by multiplying the budget by the given percents, subtract to find savings, and then find what percent the savings represents by dividing savings by the total budget.
