Percent Problems

A percent is a way to express a number as a fraction of 100. It is denoted by the symbol '%'. For example, 25% means 25 out of 100.

To find what number a percent is of, you can use the formula: Part = Percent × Whole. Rearranging gives Whole = Part / Percent.

To find the number, use the formula: Number = Part / (Percent / 100). Here, Number = 12 / (25 / 100) = 48.

The formula to find the percent of a number is: Percent = (Part / Whole) × 100.

Use the formula: Number = Part / (Percent / 100). Here, Number = 50 / (40 / 100) = 125.

To calculate what percent one number is of another, use the formula: Percent = (Part / Whole) × 100.

To find this, use the formula: Percent = (60 / 150) × 100 = 40%.

Sales tax is a percentage added to the price of goods and services, collected by the seller and paid to the government.

Sales Tax = Total Paid - Price. Here, Sales Tax = $25.02 - $24 = $1.02. Sales Tax Rate = (Sales Tax / Price) × 100 = (1.02 / 24) × 100 = 4.25%.

Use the formula: Percent = (18 / 60) × 100 = 30%.
