What is a percentage?

A percentage is a ratio that represents a fraction of 100. It is commonly used to express values or quantities in relation to a whole, where 100% represents the entire amount. Percentages are often used in calculations, comparisons, and measurements to provide a more convenient way to understand and interpret data.

How do you convert a fraction to a percentage?

To convert a fraction to a percentage, you first divide the numerator by the denominator to get a decimal. Then, multiply that decimal by 100 to convert it to a percentage. The resulting number is your fraction expressed as a percentage.

How do you convert a decimal to a percentage?

To convert a decimal to a percentage, you simply multiply the decimal by 100. This will give you the equivalent percentage value. For example, if you have a decimal of 0.75, you would multiply 0.75 by 100 to get 75%.

How do you find the percentage increase or decrease?

To find the percentage increase or decrease, you subtract the original value from the new value to get the difference. Then, divide the difference by the original value and multiply by 100 to get the percentage change. If the result is positive, it's a percentage increase. If it's negative, it's a percentage decrease.

How do you find the original quantity given the percentage increase or decrease?

To find the original quantity given a percentage increase or decrease, you can use the formula: Original Quantity = Final Quantity / (1 + increase/decrease as a decimal) for an increase, or Original Quantity = Final Quantity / (1 - decrease/increase as a decimal) for a decrease. For example, if a quantity increased by 20%, you would divide the final quantity by 1.20 to find the original quantity, and if a quantity decreased by 15%, you would divide the final quantity by 0.85 to find the original quantity.

How do you calculate the percent of a number?

To calculate the percent of a number, you first need to convert the percentage to a decimal by dividing it by 100. Then, multiply this decimal by the number you want to find the percentage of. Finally, the result will give you the percent of the number. The formula is: (Percentage / 100) x Number.

How do you solve word problems involving percentages?

To solve word problems involving percentages, you first need to identify the percentage given in the problem. Then, determine what the percentage is of (the whole or total amount) and calculate it using the formula: (Percentage x Total amount) / 100. Finally, use the calculated value to solve the specific problem, whether it's finding a part of the total, increasing or decreasing a value by a certain percentage, or any other scenario presented in the word problem.

How do you calculate simple interest using percentages?

To calculate simple interest using percentages, you can use the formula: Interest = Principal x Rate x Time. Firstly, convert the percentage rate into a decimal by dividing it by 100. Then, plug in the values of the principal amount, the rate in decimal form, and the time period in years into the formula to find the total interest accrued on the principal amount.

How do you calculate discounts and sale prices using percentages?

To calculate discounts and sale prices using percentages, you multiply the original price by the discount percentage. For example, if an item is originally priced at $50 and is discounted by 20%, you would multiply $50 by 0.20 to find the discount amount ($10). Then, subtract the discount amount from the original price to find the sale price ($40).

How do you calculate tax and tip using percentages?

To calculate tax and tip using percentages, first determine the percentage rate for both tax and tip. Next, calculate the tax amount by multiplying the pre-tax total by the tax rate (e.g., 8% tax on a $50 bill would be calculated as $50 x 0.08 = $4). To calculate the tip, multiply the pre-tax total by the tip rate (e.g., 15% tip on a $50 bill would be calculated as $50 x 0.15 = $7.50). Finally, add the tax amount and tip amount to the pre-tax total to get the total amount owed.
