Percent of a number
Find a percentage of a quantity and recover a missing part or whole
Problem types
- Percent of a quantity
- Rename percents, fractions and decimals
- Raises and earnings over years
- Estimate a percent with benchmarks
- Read a percent from a hundredths grid
- Convert percents and find the whole or the percent
- Read a circle graph
- A fraction as a decimal and a percent
- Mixed-number quantity at a unit price, then a discount
- Two percents of a whole
- Percent shares, then the rest or the difference
- Show the work: percents of a total, forward and back
Builds on
- Equivalent ratios
- Decimal place value through thousandths · Earlier idea
A percent is hundredths, so a decimal to the hundredths place is read as a percent.
- Tenths and hundredths as decimals · Earlier idea
Tenths and hundredths name fractions with denominator 10 and 100. A percent is a fraction with denominator 100, so a decimal and a percent are the same amount written with the point moved two places.
- A fraction times a whole number · Useful idea
A percent of a quantity is a fraction of the quantity, so 25 percent of 40 is 1/4 of 40.
- Fractions shown by a model · Earlier idea
A percent is a fraction with denominator 100, so a fraction model with 100 equal parts shows a percent.
- Recognizing equivalent fractions · Useful idea
A fraction is renamed as a percent by finding an equivalent fraction with denominator 100.
- Picture graphs and bar graphs · Earlier idea
The share of each bar in the total is a percent, and a circle graph shows those percents as parts of a whole.
- Coins and bills · Useful idea
A quarter is 25 percent of a dollar, so coin values name percents of a dollar.
- Halves and quarters of a whole · Useful idea
One half is 50 percent and one quarter is 25 percent, which a percent grid shows by shading equal parts.
