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 ProblemsEssential 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.

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.
