How can you convert among fractions, decimals, and percents

Step-by-step explanation:

Changing Percents to Decimals

The word percent means "per 100."  20% means 20 out of 100, or 20/100.   67% means 67 out of 100, or 67/100.  So to change a percent to a decimal, you simply divide the percentage number by 100.  When you divide by 100, the decimal just moves over 2 places to the left.

Changing Percents to Fractions

Remember, the word percent means "per 100."  This means you can change a percent to a fraction by dividing by 100.  Don't stop here though, make sure to simplify the fraction if possible.  Look to see if the numerator and denominator can be divided by the same number.

Changing Decimals to Fractions

First, figure out the place value of the last digit on the right.  Is it in the tenths place? Hundredths? Thousandths?  Use the place value to write the decimal as a fraction over 10, 100, 1000, etc. Then simplify the fraction if possible.

Remember, the first place to the right of the decimal is the tenths place.  The second place is the hundredths, then thousandths, ten thousandths, and so on.
