Tips for Adding and Subtracting Percent and Decimals - Before you get started with the addition and subtraction of percent and decimals, keep in mind that you should have clear concepts about percent and decimals. Keep in mind that the percent are a percentage or a proportion of a number. For example, the 10% of 240 is 24. And a decimal number is a number with a point/decimal in between in it. Well, this is easy. But what when you get to add or subtract these percent and decimals? In this guide, we share with you a few tips for adding and subtracting percent and decimals. Make sure to read the problem or equation thoroughly. Take the percent number and convert it into a decimal number. For example, you have an equation to solve; 22.64 + 10%. First, convert the 10% into a decimal number. The number becomes 0.01. Now, you have both the numbers in the decimal form and they are ready to be added. Place one decimal number under the other and make sure the decimal falls in line. Now add the two number and round off the answer. The same method is applicable for problems with subtraction. A series of worksheets and lessons that show students find sums and differences of percentages and decimals.
