Adding Question 1:

When you add fractions the easiest way to do it is if you find the common denominators.Once you find the common denominator than you can add the numerators and fiond your answer.

Adding Question 2:


Subtracting Question 1:

When you subtract fractions the easiast way to do it is also find the common denominator.The common denominator helps you because you wont need to subtract the denominators anymore,only the numerators.



Multiplying 1:


When multiplying Fractions all you need to do is multiply the denominators and then multiply the numerators.




Multiplying 2:

Multiplying 3:


4/6 x 2/4 = 8/24


4x2=8

6x4=24







Dividing Question 1:


When you Divide fractions the easiest way to do it is to use the Reciprical. The Reciprical is the fraction in reverse.Any time you use it, the answer should equal to one.





Dividing Question 2:

Dividing Question 3:








Word Problem:
2) It takes 2 1/4 scoops of flour to make one cake. How many cakes do 15 scoops make?

15 scoops will make 6 1/2 cakes.

- First make the denominators the same by multiplying the denominators together, or finding the number that they can both go into.
- Add numerator to numerator and denominator to denominator
- You could simplify if the numerator and denominator are not prime numbers

Adding Fractions





Subracting Fractions



When subracting mixed numbers, the first thing you do is turn the fractions into improper fractions. Next, you find the lowest common denominator. Once you have the LCD, subtract the numerators and keep the denominator. Lastly, you must simplify the fraction.
