Multiplying Fractions and
Whole Numbers
Essential Understanding:
To multiply a fraction by a whole number, begin by
converting the whole number to an improper fraction by
placing a 1 as it’s denominator. Then simply multiply
numerator by numerator and denominator by
denominator (straight across). Write the product in
simplest form.

Multiplying Fractions and
Mixed Numbers
Essential Understanding:
To find the product of fractions and mixed numbers, begin by
converting the mixed number to and improper fraction. This is
done by adding the numerator to the product of the denominator
and whole number. (leave room for example).
Example:
Next simply multiple numerator by numerator and denominator
by denominator (straight across). Finally write the product in
simplest form.

Solve multiplication story
problems involving fractions.
Story Problems
Essential Understanding:
Sometimes fractions are presented in number form ( ½ ).
Sometimes they are given in word form (three fourths) But,
sometimes they are hidden in the wording. For example, the
phrase “out of” signifies a part to whole relationship. Three “out
of” four dentist recommend trident.
When solving story problems we look for key phrases we can use
to identify the proper operation. This remains true for story
problems involving fractions.
For Example: “Howard spent 3/5 of his allowance.” Many times a
fraction followed by the word of tells us to multiply.

Estimate the product of
fractions using compatible
numbers and rounding.

Study Guide
Let’s Review
Rounding Fractions:
Think: “Is the fraction closer to 0, ½, or 1” If the
numerator is almost as big as the denominator round
up to the next whole number. If the numerator is much
smaller than the denominator, round down to the
closest whole number.
