  2. Times You Would Multiply a Fraction Times a Whole Number • You walk a 4 mile route halfway. ½ of 4 or ½ x 4 • You walk a ¾ mile route twice. 2 x ¾

  3. Times You Would Multiply a Fraction Times a Whole Number • A $12 ticket to the magic show is on sale for 2/3 of the original price. 2/3 of $12 or 2/3 x 12

  4. How to Find the Fraction of a Whole Number • The first thing to remember is “of” means multiply in mathematics. of x =

  5. How to Find the Fraction of a Whole Number • Step 1 - When you see a fraction problem you know when you read “of” in the problem you multiply. 1 x of 46 2

  6. How to Find the Fraction of a Whole Number • Step 2 – Change your whole number to a fraction by adding a one underneath. 1 x 46 2 1

  7. How to Find the Fraction of a Whole Number • Step 3 – Multiply your numerators straight across. 1 x 46 46 = 2 1

  8. How to Find the Fraction of a Whole Number • Step 4 – Then multiply your denominators straight across. 1 x 46 46 = 2 1 2

  9. How to Find the Fraction of a Whole Number • Step 5 – Simplify your answer. In this case we change an improper fraction to a mixed number or a whole number. 23 1 x 46 46 2) = 46 2 1 2
