Percents, Decimals, and Fractions Textbook Pages Monday January 13th

Objective I can write equivalent percents, fractions, and decimals.

Writing fractions as Percents! If Max made 7 out of 10 free throws and John made 17 out of 25 free throws. Who had a better percent? First write each result as a fraction Then write an equivalent fraction with a denominator of 100 to find the percent.

7/1017/25 __/100___/100 70/10068/100 70%68% Remember when making equivalent fractions whatever you do to the bottom you do to the top.

Try some ¾ 75% 7/20 35% 3/25 12%

Is there another way to find the percent from a fraction. Just divide the fraction out to find the decimal.

Write decimals as Percents Remember when we changed a percent to a decimal we divided by 100. Just like most things in math, in order to undo something we do the opposite. To change a decimal to a percent, multiply by 100.

Making decimal a percent 0.27 Take this and multiply by 100 to get the percent x 100 = 27% Or move the decimal two spots to the right.

Another way! You can read the decimal and make a fraction> 0.25 You would read this how? Twenty hundredths, which means 25 over /100 Which is 25%

Try Some % %

Benchmark Percents, Fractions, Decimals You can use benchmark percent to write other percents, decimals, or fractions. Use benchmark percents to help you locate where others may fall.
