Presentation transcript:

By the end of this lesson you will be able to explain/calculate the following: 1. Fractions on your calculator 2. Converting fractions to decimals 3. Converting fractions to percentage

 There are many essential skills that you will need with fractions.  You should be able to: 1. simplify fractions 2. convert between improper fractions & mixed numbers. 3. use your calculator efficiently.

 Writing fractions with the same denominator allows us to compare the size of fractions.

 Another way of writing fractions in order is to convert each fraction to a decimal before comparing them. divide numerator by denominator  To convert a fraction to a decimal, divide the numerator by the denominator.

does not terminates  Sometimes the conversion of a fraction to a decimal does not produce a decimal that terminates. division continued recurring evident  If this is the case, a recurring decimal results, and the division should be continued until the recurring portion of the decimal is evident.  Recurring decimals infinite  Recurring decimals have an infinite number of decimal places.

 To convert a fraction to a percentage, multiply the fraction by 100 and include the % sign.
