Parts of a Fraction A fraction is a part of a whole Top number = numerator Number of parts you have Bottom number = denominator Number of parts the whole is divided into Example: Click to return to the main menu!

Reducing Fractions Click to return to the main menu!

Improper Fractions Top number (numerator) is larger than the bottom number (denominator) Also called “top-heavy” fractions These are NOT bad fractions! Example: Click to return to the main menu!

Proper Fractions Top number (numerator) is less that the bottom number (denominator) Used often in everyday life Examples: Proper fractions are used for ingredients on a recipe (1/4 cup of sugar) Proper fractions are used often when telling time (1/2 past 3 o’clock) Example: Click to return to the main menu!

Adding and Subtracting Fractions Same DenominatorsDifferent Denominators 1. List the multiples of each denominator until you find a number in common (this becomes the least common denominator). 2. Form equivalent fractions by multiplying the numerator and denominator by a number that gives new fractions with the least common denominator. 3. Add/subtract the numerators and put them over the least common denominator. Example: Click to return to the main menu!

Multiplying and Dividing Fractions Multiplying 1. Multiply the top numbers (numerators) 2. Multiply the bottom numbers (denominators) 3. Simplify answer if needed. Example: Dividing Click to return to the main menu!

Fractions in Word Problems Read and re-read the problem carefully. Write down any information that you believe is important. Decide which operation is being used. Apply your knowledge that you learned from the other links to solve. Example: Will ran 1/2 of a mile, and Bob ran 1/3 of a mile. How much farther did Will run? Key facts: Will= 1/2 of a mile; Bob ran 1/3 of a mile Operation: Subtraction Solution: 1/2 - 1/3 =3/6 – 2/6= 1/6 Will ran 1/6 of a mile farther than Bob. Click to return to the main menu!

Question Grandma is making cookies, and her recipe calls for 2/3 cup of flour. If she wants to cut her recipe in half, how much flour will Grandma need? (Hint: first determine the operation being used and be sure to simplify your final answer.) A. 4/3 cup of flour B. 1/6 cup of flour C. 1/3 cup of flour D. 2/6 cup of flour

Oops…Try Again! It seems that you used multiplication to double the recipe. (2/3 x 2 = 4/3) Check your work, and rethink the operation being used. Click to return to the review question!

Oops…Try Again! You must’ve accidentally used subtraction! (2/3-1/2=1/6) Go back and focus on the words “cut the recipe in half” to use the correct operation. Click to return to the review question!

Correct! Click to move forward!

Oops…Try Again! You almost got it! Revisit your answer, and make sure it is in the simplest form. Click to return to the review question!
