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

  3. 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

  4. 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

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

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

  7. 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
