Decimals Percent Worksheets
These decimal percent worksheets help students practice converting between decimals and percentages while solving real-world problems. The collection includes converting decimals to percents, finding percentages of decimal numbers, and calculating percent increases or decreases with decimal values.
About these worksheets
These worksheets cover finding percentages of quantities using multiple methods. Students break numbers into tens and ones to calculate percents, find a percent of whole numbers and decimals, increase and decrease amounts by a percentage, determine what percent one number is of another, find percent of fractions, calculate percent increase and decrease, and determine spinner probability. Spanning sixth through seventh grade.
Calculate Percentage by Breaking Down Numbers
- Find a percent of a number by splitting the number into tens and ones.
- Use 10% and 1% as quick benchmarks to build other percentages.
- Add the partial percent amounts together to get the final answer.
- Work with percent problems that include decimal answers when needed.
Finding Percent of Number
- Practice figuring out what percent one number is of another (e.g., "30 is what percent of 69?")
- Divide the part by the whole and multiply by 100 to convert to a percent
- Round decimal percents to the nearest hundredth
Finding Percent of a Decimal
- Find a given percent of a decimal by multiplying.
- Convert a percent to a decimal so it’s easier to calculate.
- Keep decimal points lined up and place the decimal correctly in the final answer.
- Understand that “percent of” means taking part of an amount.
Adding and Subtracting Percents and Decimals
- Increase a number by a given percent to find the new amount.
- Decrease a number by a given percent to find the new amount.
- Round the final answer to the place value asked for.
Adding and Subtracting Percents of a Quantity
- Add a percent of a quantity to the original amount to find an increased total.
- Subtract a percent of a quantity from the original amount to find a decreased total.
- Decide whether a situation calls for adding or subtracting the percent part from the whole.
Examining Percent Increase and Decrease
- Find the percent increase when a value goes up from an original amount to a new amount.
- Find the percent decrease when a value goes down from an original amount to a new amount.
- Subtract to find the amount of change between the original and new values.
- Use division and multiplying by 100 to turn the change into a percent.
Determining Spinner Percent Chance
- Count how many equal sections are on a spinner and how many match a given number.
- Convert a probability into a percent chance.
About these worksheets
These worksheets provide practice converting between decimals and percents in both directions. Students multiply and divide by 100, move decimal points, and work with values less than one. These fundamental conversion skills support work with fractions, decimals, and percents across all grade levels.
Converting Decimal to Percent
- Turn a decimal into a percent by multiplying by 100.
- Move the decimal point two places to the right to write a percent.
- Write the final answer using the percent sign (%) correctly.
- Convert decimals that are less than 1, equal to 1, or greater than 1 into percents.
Converting Percent to Decimal
- Convert a percent into a decimal by dividing by 100.
- Move the decimal point two places to the left to change a percent to a decimal.
- Write percents as decimals in standard decimal notation (like 0.25 instead of 25%).
Converting A Decimal To Percent (Less than 1)
- Practice turning a decimal less than 1 into a percent.
- Learn to multiply a decimal by 100 to find the percent.
- Get comfortable moving the decimal point two places to the right when converting to percent.
- Write the final answer correctly using the percent sign (%)
Converting A Percent To a Decimal (Less than 1)
- Convert a percent to a decimal by dividing by 100.
- Move the decimal point two places to the left when changing a percent into a decimal.
- Write the decimal in correct place value form (tenths, hundredths, thousandths).
- Recognize that percents under 100% turn into decimals less than 1.
