|
|
|
What is a numerator?
|
The numerator is the top number of a fraction. This number represents the portion of the whole number left.
|
Ex. 3/4 or 3 over 4, would be have a numerator of 3. There are 3 pieces of a pie that was cut into 4 equal pieces left.
|
|
|
What is a denominator?
|
The denominator is the number on the bottom of a fraction.
|
Ex. 25/100 or 25 over 100, would have a denominator of 100. There are 25 cookies out of the 100 you started with left to eat.

How to use conversion for decimals to fractions.

equivalent fractions
|
Equivalent fractions are the same amounts even if the fractions have different numbers in the numerator and denominator spaces.
|
Ex. A whole number is the # you start with for a particular object. You can use the same pie to show the same fraction or portion used in differents ways. For example, 1/2 can also mean 3/6. That is because the whole pie was divided into half (1/2) meaning two large pieces. It can also be cut into those two large pieces and cut again to represent the same amount of pie, but smaller servings.
