Converting Fractions to Decimals to Percents

To change from a fraction to a decimal, divide the denominator into the numerator. To change from a decimal to a percent, move the decimal two places to the right. To change from a percent to a decimal, move the decimal two places to the left (remember that if there is no decimal there is always one to the right of the number). To change from a decimal to a fraction, read the number as a decimal then right it as a fraction, then reduce.
