The top term in a fraction is called the numerator.

You can rewrite a fraction to higher terms by adding the numerator and the denominator.

An improper fraction has a value equal to or less than 1.

In converting mixed numbers to improper fractions, the numerator of the improper fraction will be the same as the numerator of the fractional part of the mixed number.

A fraction is in lowest terms when there is no number that can be divided evenly into the numerator and denominator.

Before fractions may be added or subtracted, they must all have the same:

To convert mixed numbers to improper fractions, multiply the whole number times the denominator of the fraction and add the product to the original denominator.

When multiplying two proper fractions, the product:

Reducing before multiplying

A fraction with a numerator that is less than the denominator is called an improper fraction.

To divide by a fraction, divide the dividend by the reciprocal of the dividend.

Before you can add or subtract fractions, they must have the same denominators.

If you multiply or divide both parts of a fraction by the same number, the value of the fraction does not change.

Raising a fraction to higher terms changes the value of the fraction.

Multiplication and division of fractions are totally dissimilar activities requiring separate skills.
