What are Fractions?
By: Greg StarkEC&I 831
What are fractions?
• They are used when we want to count how much of something we have when we don’t have the whole thing.
Numerator--------------------Denominator Represents the number of parts into
which the whole has been divided
Represents the number of partsof a whole we have.
For example:
34
712
Remember:
• A fraction must relate to something to have meaning – what is ½?
• We need to have ½ of something (the whole) for it to make sense:
½ a cup, ½ a tank of gas,½ an hour, or ½ an orange
