copyright©amberpasillas2010 Here is an example of when you would multiply a mixed number times a fraction. In a car race, the track is 3 miles long. If the car breaks down way through the course, how far did you go?

copyright©amberpasillas2010 Step 1 - When you see a fraction problem you know when you read “ of ” in the problem you multiply. of x

copyright©amberpasillas2010 Step 2 – Change the mixed number to an improper fraction. x x

copyright©amberpasillas2010 Step 3 – Multiply the numerators straight across. x =

copyright©amberpasillas2010 Step 4 – Multiply the denominators straight across. x = 18

copyright©amberpasillas2010 Step 5 – Simplify your answer. In this case change the improper fraction to a mixed number. x = )

copyright©amberpasillas Change the mixed numbers to improper fractions. 2. Multiply the numerators straight across. 3. Multiply the denominators straight across. 4. Simplify or reduce if possible. When multiplying fractions, you DO NOT need a common denominator.
