2. What fraction of the candy is orange? 3939 The number that tells how many equal parts are described is the numerator. The number that tells the number of equal parts in the whole is called the denominator. A fraction is a way of representing part of a whole or part of a group.

3. The pizza has been cut into three equal parts. We call these thirds. A third is written as 1313.

4. The whole pizza cut into three equal parts gives us thirds. Think about just one slice. We can write this using a fraction 13.13.

5. Think about two slices. Two slices is two thirds. We can write two thirds as 2 3. The top number of the fraction tells us how many slices we have. We call it the numerator. The bottom number tells us how many parts in the whole pizza. We call it the denominator.

6. If all the pieces of a whole are present, we call that 1 whole. Since 6 slices of the cake are present, we can say that 6666 = 1 whole

7. Here are all the fractions you can make from a cake cut into six slices.

8. 3636

10. Equivalent Fractions name the same amount. 1 2 4 2 4 and 8 are equivalent fractions. 01 1212 01 01 1414 3434 2424 4848 1818 2828 3838 5858 6868 7878

11. To find equivalent fractions, you can multiply the numerator and denominator of a fraction by the same nonzero number. 2525 = 2 x 2 5 x 2 = 4 10 2525 = 2 x 3 5 x 3 = 6 15 2525 =

12. Compare 1212 and 3737 1. Multiply 1212 x 3333 = 3636 2. Compare 3636 and 3737 Since 3636 is not the same as 3737 these fractions are not equivalent,

13. A fraction is in simplest form when its numerator and denominator have no common factors other than 1.

14. 1 Divide the numerator and the denominator by a common factor. 6 18 ÷ = 6 18 ÷ 3333 = 2626 2 Keep dividing by common factors until the only common factor is 1. 3 is a common factor of 6 and 18. 2626 = 2626 ÷ ÷ 2222 = 1313 2 is a common factor of 2 and 6. 1 and 3 have no other common factor greater than 1.
