Whether you’re trying to calculate a discount during a sale or determine the tip at a restaurant, these strategies will come in handy.
Useful strategies for calculating percentages mentally
Divide and multiply: One of the simplest ways to calculate percentages mentally is by dividing the number by 100 and then multiplying it by the percentage you need. For example, if you want to find 20% of 80, divide 80 by 100 (0.8) and then multiply it by 20, resulting in 16.
Round and adjust: Another helpful technique is to round the numbers to make the calculation easier. For instance, if you need to find 35% of 68, you can round 68 to 70 and calculate 10% of 70 (7) and then multiply it by 3, resulting in 21.
Use fractions: Sometimes, it’s easier to work with fractions instead of percentages. For example, if you want to find 75% of 80, you can convert 75% to the fraction 3/4 and multiply it by 80, resulting in 60.
Reverse percentages: If you know the final amount and want to find the original value, you can use reverse percentages. For instance, if you have 80 and want to find what percentage it is of 100, divide 80 by 100 (0.8) and multiply it by 100, resulting in 80%.
Common mistakes to avoid when solving percentage problems
Forgetting to convert percentages to decimals: Many people forget to convert percentages to decimal form before performing calculations. Always remember to divide the percentage by 100 or move the decimal point two places to the left.
Misinterpreting the problem: It’s essential to understand the context of the problem and what the percentage represents. Read the question carefully to avoid solving the wrong calculation.
Using incorrect formulas: Make sure you’re using the correct formula for the specific percentage problem you’re trying to solve. Different scenarios may require different formulas, so double-check your approach.
